+#### message
+- err access line response.cpp:169
+- g pas fini la gestion de sortie du cgi (comparaison des headers fields pour supprimer les doublons)
+- g rendu independantes les fonctions qui parses un message http (requete ou response) dans `parsing_http_message.cpp`
+- il y a une erreur importante dans la fonction qui parse les headers d'un message http : ca ne verifie pas si la premier ligne est un header ou la "first line"
+
+#### TODO
+- `_is_cgi()` and `_fill_cgi_path()`
+- `_cgi_output()` change status in `client->status`
+- two cgi tests :
+?	- a basic form with "name" and "something", that return a html page with that
+?		- for GET and POST
+?	- a script called by a file extension in URI
+
+#### output cgi script :
+!	TODO : change all the '\n' by '\r\n'
+!	TODO : there is at least one header field followed by '\r\n\r\n' :
+			- "Content-Type"
+			- "Location"
+			- "Status"
+!	TODO : there is no space between filed name and ":"
+!	TODO?: handle Location field, either :
+			- local : start with '/' --> rerun the request with new uri
+			- client : start with '<scheme>:' --> send back status code 302
+->	TODO : there is no field duplicate (resolve conflicts)
+->	TODO : if status field, change server status for this one
+->	TODO : if no Location field && no Status field -> status code = 200
+
+#### questions
+- in client.cpp i fill the port, is there a default one in case it's not in the request ?
+- timeout server but still works ?
+- path contains double "//" from `Webserv::_get()` in response.cpp
+- cgi path ? defined in config ? and root path ? :
+	- `Client.cpp : fill_script_path()`
+	- `cgi.cpp : is_cgi()`
+	- `cgi.cpp : set_env()`
+- what if the uri contains a php file, and the config said php must be handled by cgi, but the path to this php in the uri is wrong ?
+	- is it ok ? `http://my_site.com/cgi-bin/php-cgi` (real path)
+	- is it ok ? `http://my_site.com/php-cgi` (reconstruct path ?)
+	- is it ok ? `http://my_site.com/something/php-cgi` (what about 'something' ?)
+	- is it ok ? `http://my_site.com/something/cgi-bin/php-cgi` (real path with 'something' before ? )
+- I don't save the STDIN and STDOUT before dup2 in child process, is it wrong ?
+- the response page is received long after the cgi-script is done, why ?
+
+#### notifications
+- i changed the Client getters in two categories :
+	- getters for requests infos : `get_rq_<info>`
+	- getters for client sides infos : `get_cl_<info>` (such as ip of client)
+- i changed the variables in request struct in Client :
+	- `path` become `uri` (ex. `/path/to/file?var=val`)
+	-  add `abs_path`     (ex. `/path/to/file`        )
+	-  add `query`        (ex.               `var=val`)
+- the header fields names, as key in map, are stored in lowercase, and getters are case-insensitives

+## man
+
+- **htons, htonl, ntohs, ntohl :** converts the unsigned short or integer argument between host byte order and network byte order
+- **poll :** waits for one of a set of file descriptors to become ready to perform I/O
+	- alternatives : select, epoll (epoll_create, epoll_ctl, epoll_wait), kqueue (kqueue, kevent)
+- **socket :** creates an endpoint for communication and returns a file descriptor that refers to that endpoint
+- **listen :** marks a socket as a passive socket, that is, as a socket that will be used to accept incoming connection requests using accept()
+- **accept :** used with connection-based socket types. It extracts the first connection request on the queue of pending connections for the listening socket, creates a new connected socket, and returns a new file descriptor referring to that socket. The newly created socket is not in the listening state. The original socket is unaffected by this call
+- **send :** (~write) used to transmit a message to another socket. May be used only when the socket is in a connected state (so that the intended recipient is known). The only difference between send() and write() is the presence of flags. With a zero flags argument, send() is equivalent to write()
+- **recv :** (~read)  used to receive messages from a socket. May be used to receive data on both connectionless and connection-oriented sockets. The only difference between recv() and read() is the presence of flags. With a zero flags argument, recv() is generally equivalent to read()
+- **bind :** associate a socket fd to a local address. When a socket is created with socket(), it exists in a name space (address family) but has no address assigned to it. It is normally necessary to assign a local address using bind() before a socket may receive connections (see accept())
+- **connect :** connects a socket fd to a remote address
+- **inet_addr :** converts the Internet host address cp from IPv4 numbers-and-dots notation into binary data in network byte order. Use of this function is problematic because in case of error it returns -1, wich is a valid address (255.255.255.255). Avoid its use in favor of inet_aton(), inet_pton(), or getaddrinfo()
+- **setsockopt :** manipulate options for a socket fd. Options may exist at multiple protocol levels; they are always present at the uppermost socket level
+- **getsockname :** returns the current address to which a socket fd is bound
+- **fcntl :** manipulate an open fd, by performing some actions, like duplicate it or changing its flags

+## todo
+
+- [ ] read the RFC and do some tests with telnet and NGINX
+#### parsing config
+- [ ] Your program has to take a configuration file as argument, or use a default path.
+- [ ] Choose the port and host of each ’server’.
+- [ ] Setup the server_names or not.
+- [ ] The first server for a host:port will be the default for this host:port (that means it will answer to all the requests that don’t belong to an other server).
+- [ ] Setup default error pages.
+- [ ] Limit client body size.
+- [ ] Setup routes with one or multiple of the following rules/configuration (routes wont be using regexp):
+	- [ ] Define a list of accepted HTTP methods for the route.
+	- [ ] Define a HTTP redirection.
+	- [ ] Define a directory or a file from where the file should be searched (for example, if url /kapouet is rooted to /tmp/www, url /kapouet/pouic/toto/pouet is /tmp/www/pouic/toto/pouet).
+	- [ ] Turn on or off directory listing.
+	- [ ] Set a default file to answer if the request is a directory.
+	- [ ] Execute CGI based on certain file extension (for example .php).
+	- [ ] Make the route able to accept uploaded files and configure where they should be saved.
+#### connection basic
+- [ ] You can’t execve another web server.
+- [ ] Your server must never block and the client can be bounced properly if necessary.
+- [ ] It must be non-blocking and use only 1 poll() (or equivalent) for all the I/O operations between the client and the server (listen included).
+- [ ] poll() (or equivalent) must check read and write at the same time.
+- [ ] You must never do a read or a write operation without going through poll() (or equivalent).
+- [ ] Checking the value of errno is strictly forbidden after a read or a write operation.
+- [ ] You don’t need to use poll() (or equivalent) before reading your configuration file. Because you have to use non-blocking file descriptors, it is possible to use read/recv or write/send functions with no poll() (or equivalent), and your server wouldn’t be blocking. But it would consume more system resources. Thus, if you try to read/recv or write/send in any file descriptor without using poll() (or equivalent), your grade will be 0.
+- [ ] You can use every macro and define like FD_SET, FD_CLR, FD_ISSET, FD_ZERO (understanding what and how they do it is very useful).
+- [ ] A request to your server should never hang forever.
+- [ ] Your server must be compatible with the web browser of your choice.
+#### parsing request HTTP (fields, ...)
+- [ ] We will consider that NGINX is HTTP 1.1 compliant and may be used to compare headers and answer behaviors.
+#### response HTTP (fields, ...)
+- [ ] Your HTTP response status codes must be accurate.
+- [ ] You server must have default error pages if none are provided.
+- [ ] You can’t use fork for something else than CGI (like PHP, or Python, and so forth).
+- [ ] You must be able to serve a fully static website.
+#### upload files
+- [ ] Clients must be able to upload files.
+#### CGI
+- [ ] You need at least GET, POST, and DELETE methods.
+- [ ] Do you wonder what a CGI is?
+- [ ] Because you won’t call the CGI directly, use the full path as PATH_INFO.
+- [ ] Just remember that, for chunked request, your server needs to unchunked it and the CGI will expect EOF as end of the body.
+- [ ] Same things for the output of the CGI. If no content_length is returned from the CGI, EOF will mark the end of the returned data.
+- [ ] Your program should call the CGI with the file requested as first argument.
+- [ ] The CGI should be run in the correct directory for relative path file access.
+- [ ] Your server should work with one CGI (php-CGI, Python, and so forth).
+#### write tests
+- [ ] Stress tests your server. It must stay available at all cost.
+- [ ] Do not test with only one program.
+- [ ] Write your tests with a more convenient language such as Python or Golang, and so forth. Even in C or C++ if you want to
+#### persistent connexion
+- [ ] Your server must be able to listen to multiple ports (see Configuration file)
+- [ ] Your server should never die.

+## cgi rfc
+[rfc 3875](https://www.rfc-editor.org/rfc/rfc3875)
+
+#### summary :
+- the cgi-script will send back at least one header field followed by an empty line
+- this header field will be one of three :
+	- "Content-Type"
+	- "Location"
+	- "Status"
+- the cgi-script may send back more header fields
+- the server must check and modify few things :
+	- there is no duplicate in headers fields (if there is, resolve conflict)
+	- there is no space between the field name and the ":"
+	- the newlines are of form "\r\n", and not "\n" only
+	- if the location field is not present, then if the status field is not present either, then the status code is 200
+	- the cgi-script can return a location field, of two types :
+		- local redirection : start with a "/", the server must answer as if this was the request uri
+		- client redirection : start with <name-of-cheme>":", the server must send back a status 302 with this uri to the client
+- to pass the body-message to the cgi-script, we write it into the temporary fd on which the script read it's standard input
+
+[3.1: server responsabilities](https://www.rfc-editor.org/rfc/rfc3875#section-3.1)
+
+- The server [...] receives the request from the client
+- selects a CGI script to handle the request
+- converts the client request to a CGI request
+- executes the script and converts the CGI response into a response for the client
+
+[3.3: script uri](https://www.rfc-editor.org/rfc/rfc3875#section-3.3)
+
+- the 'Script-URI' [...] MUST have the property that if the client had accessed this URI instead, then the script would have been executed
+
+[4: how the server prepare the cgi requests](https://www.rfc-editor.org/rfc/rfc3875#section-4)
+
+- the cgi receives 2 differents set of informations :
+	- the request meta-variables (in UNIX, by env variables)
+	- and the message-body
+
+[4.1: request meta-variables](https://www.rfc-editor.org/rfc/rfc3875#section-4.1)
+
+- a header field that spans multiple lines MUST be merged onto a single line
+
+[4.2: request message-body](https://www.rfc-editor.org/rfc/rfc3875#section-4.2)
+
+- unless defined otherwise, the script access request data by reading stdin
+
+[6: how the response from the script is returned to the server](https://www.rfc-editor.org/rfc/rfc3875#section-6)
+
+- The response comprises 2 parts, separated by a blank line :
+	- a message-header
+	- and a message-body
+- The message-header contains one or more header fields
+- The body may be NULL
+
+[6.2: responses types](https://www.rfc-editor.org/rfc/rfc3875#section-6.2)
+
+- four types of responses :
+	- document response
+	- local redirect response
+	- client redirect response
+	- client redirect response with document
+- document response :
+	- it must return a Content-Type header field
+	- a Status-Header field is optional (200 is assumed if omited)	
+	- the server must check the cgi-script output, and modifie it to comply with the protocol version
+- local redirect response :
+	- it must return only a Location field
+	- it contains a local path URI and query string ('local-pathquery')
+	- the local path URI must start with a "/"
+	- the server must generate the response for this local-pathquery
+- client redirect response :
+	- it must return only a Location field
+	- it contains an absolute URI path, to indicate the client that it should reprocess the request with this URI
+	- the absolute URI always start with the name of scheme followed by ":"
+	- the http server must generate a 302 'Found' message
+- client redirect response with document
+	- it must return a Location field with an absolute URI path
+	- it must return the Status header field, with a value of 302 'Found'
+	- the server must check the cgi-script output, and modifie it to comply with the protocol version
+
+[6.3: cgi header fields](https://www.rfc-editor.org/rfc/rfc3875#section-6.3)
+
+- whitespace is permitted between the ":" and the field-value
+- but not between the field-name and the ":"
+- the CGI script can set three differents fields :
+	- Content-Type
+	- Location
+	- Status
+- Content-Type :
+	- if there is a body in the response, a Content-Type field must be present
+	- if there is no Content-Type, the server must not attempt to determine one
+- Location :
+	- the local URI path must be an absolut path, not a relative path, nor NULL
+	- the local URI path must, then, start with "/"
+	- the absolut URI start with "<name-of-scheme>:"
+- Status :
+	- a 3-digit integer code
+	- 4 standards :
+		- 200 'OK' indicates success, it's the default value
+		- 302 'Found' with Location header and response message-body
+		- 400 'Bad Request' an unknown request format, like missing CONTENT-TYPE
+		- 501 'Not Implemented' the script received unsupported REQUEST-METHOD
+	- construction: `Status:400 "explication of the error"\n`
+- the cgi-script can return other header fields, concerning the response message
+	- the server must translate cgi-headers syntax into http-header syntax
+	- for exemple, newline can be encoded in different ways
+- the cgi-script must not return header fields concerning client-side communication
+	- the server can remove such fields
+	- (not sure : https://www.rfc-editor.org/rfc/rfc3875#section-6.3.4)
+	- the server must resolve conflicts between script-header fields and themselves
+
+[6.3: cgi message body](https://www.rfc-editor.org/rfc/rfc3875#section-6.4)
+
+- the server must read it untill EOF
+- the server must not modify it, except to convert charset if needed

-   In many standards track documents several words are used to signify
-   the requirements in the specification.  These words are often
-   capitalized.  This document defines these words as they should be
-   interpreted in IETF documents.  Authors who follow these guidelines
-   should incorporate this phrase near the beginning of their document:

-   potential for causing harm <span class="Verified-inline-styling" id="inline-494">(e.g., limiting retransmissions)</span>  For <button id="btn_494" target="expand_494" onclick="hideFunction(&quot;expand_494&quot;)">Expand Multiple</button>

-7. Security Considerations
-
-   These terms are frequently used to specify behavior with security
-   implications.  The effects on security of not implementing a MUST or
-   SHOULD, or doing something the specification says MUST NOT or SHOULD
-   NOT be done may be very subtle. Document authors should take the time
-   to elaborate the security implications of not following
-   recommendations or requirements as most implementors will not have
-   had the benefit of the experience and discussion that produced the
-   specification.
-
-8. Acknowledgments
-
-   The definitions of these terms are an amalgam of definitions taken
-   from a number of RFCs.  In addition, suggestions have been
-   incorporated from a number of people including Robert Ullmann, Thomas
-   Narten, Neal McBurnett, and Robert Elz.
