+- how should we handle a wrong url like `http://localhost/cgi-bin/wrong.phpp/good.php` ?
+	- do we serve `./srcs/cgi-bin/good.php` ?
+	- or do we return 404 "not found" ?
+->	- for now, execve would crash, but that doesn't produce a 404 error, rather a 500, is it bad ?
+	- could we use errno after execve to choose an appropriate http error ? subject says : "Checking the value of errno is strictly forbidden after a read or a write operation"
+- if a url has a file with extension, but it's not a cgi extension, is it necessary to look further ?
+	- ex. `http://localhost/file.php/file.py` for `cgi_ext py;` ?
+- the response page is received long after the cgi-script is done, why ?

+[rfc 3875](https://www.rfc-editor.org/rfc/rfc3875)
+
+#### output cgi script :
+
+#### 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 field duplicate (resolve conflicts)
+	- there is no space between filed name and ":"
+	- change all the '\n' by '\r\n'
+	- if no Location field && no Status field -> status code = 200
+	- handle Location field, either :
+		- local : start with '/' --> rerun the request with new uri
+		- client : start with '<scheme>:' --> send back status code 302
+	- there is at least one header field followed by '\r\n\r\n' :
+		- "Content-Type"
+		- "Location"
+		- "Status"
+	- if status field, change server status for this one
+- 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

+## http errors
+
+#### HTTP Client Errors
+- 400 	Bad Request 							This error code indicates that the request cannot be processed because of wrong syntax usage by the client.
+- 401 	Unauthorized 							This error code indicates that the client is not authorized to receive the requested data, without authentication. A login name and password based authentication might be required to access the requested data.
+- 403 	Forbidden 								There is no way you can access the requested data. A 403 error announces that the data is off limits.
+- 404 	Not Found 								This error indicates that the resources requested by the client are currently unavailable.
+- 405 	Method Not Allowed 						This error indicates wrong usage of request method. Depending on the kind of data requested, the appropriate request method must be chosen.
+- 406 	Not Acceptable 							When the data provided by a web server does not match the specifications made in ‘Accept’ header of the client HTTP request, this error is the result.
+- 407 	Proxy Authentication Required 			This error clearly indicates that an authentication from the proxy server is required to gain access to requested resources.
+- 408 	Request Timeout 						This type of error indicates that the client was delayed in making a request, within the specified time allocated to it, by the server.
+- 409 	Conflict 								This error code is displayed when the server perceives a conflict between two requests made simultaneously by different clients, for the same resource.
+- 410 	Gone 									This error code indicates that the requested data is no longer hosted on the server and therefore further requests made for it, would be futile.
+- 411 	Length Required 						If the request made by the client does not include information about the length of the requested data or resource, this error code is displayed.
+- 412 	Precondition Failed 					Some requests made by clients come attached with conditions that need to be satisfied by the server, before data transaction may happen. If these conditions are not met, error 412 results.
+- 413 	Request Entity Too Large 				When a client makes a request which is too overwhelming for the server’s resources to handle, it presents this error code.
+- 414 	Requested URI Too Long 					A Uniform Resource Identifier (URI) is a character string used to describe a data stream or resource on a server. Error 414 occurs when the server is unable to process the URI, because of limited resources and long string length.
+- 415 	Unsupported Media Type 					A server may be designed to allow only certain formats for media files. When error 415 is displayed, it indicates that the format of file being uploaded through a client request, does not match the requisite format.
+- 416 	Request Range Not Satisfiable 			Sometimes, a client may request for only a small part of a file, instead of asking for the entire file. If this request is not specified properly and the part of the file requested does not exist, this error is displayed.
+- 417 	Expectation Failed 						This error code is displayed when the server cannot meet the specifications provided in the request.
+- 422 	Unprocessable Entity 					This error is displayed when the request made, cannot be processed due to an error in semantic structure.
+- 423 	Locked 									This error is displayed when a requested piece of data or resource has been locked, making it inaccessible for a server.
+- 424 	Failed Dependency			 			A server may process a succession of requests from a client with the fulfillment of each, dependent on the one made before. This error is displayed when a request made before is not fulfilled, due to which the current request cannot be processed.
+- 426 	Upgrade Required 						This error signifies that the client may need to switch over to a secure protocol like TLS to get the request processed.
+- 444 	No Response								This error signifies that the server has simply rejected the client request and terminated connection.
+- 449 	Retry With 								This is a request made by the server to the client, to make the request again after executing certain actions or making specific changes in request. This is an error code introduced by Microsoft.
+- 499 	Client Closed Request	 				When client terminates a connection made with the server, while its processing the associated request, this error code is displayed.
+- 450 	Blocked By Windows Parental Controls 	Another error code introduced by Microsoft, this one is displayed when a URL is blocked by parental control settings on the web browsers.
+
+#### HTTP Server Errors
+- 500 	Internal Server Error 					A generic message displayed by the server, when the problem with the request cannot be specified by any other appropriate code.
+- 501 	Not Implemented							This error indicates the inability of the server to process a request, as it hasn’t been configured to respond to the request method used.
+- 502 	Bad Gateway 							Sometimes, hosted pages on web servers are transmitted to client via proxy servers. If the proxy server (to which a client has sent a request), fails connecting with the web server (known as the upstream server), error 502 results.
+- 503 	Service Unavailable 					When the server is already overloaded with multiple requests, it will temporarily stop entertaining new requests, by displaying a 503 error code.
+- 504 	Gateway Timeout 						When the request made by a proxy server to the web server hosting a resource times out, error 504 is reported.
+- 505 	HTTP Version Not Supported 				An error code seen rarely, it is displayed when the web server does not support the protocol version of the client request.

 Un truc cool et surtout bien utile ici c'est d'utiliser un proxy entre ton navigateur et ton serveur pour vérifier ce qui est envoyé en raw. Les navigateurs peuvent avoir des comportements différents. 
 Vous avez des modules sur vos navigateur ou des logiciels externe. C'est assez rapide et gratuit.

-Abstract
-
-   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:

-6. Guidance in the use of these Imperatives
-
-   Imperatives of the type defined in this memo must be used with care
-   and sparingly.  In particular, they MUST only be used where it is
-   actually required for interoperation or to limit behavior which has
-   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.
