-## questions :
+## work together
+#### questions
 - in client.cpp i fill the port, is there a default one in case it's not in the request ?
 
-- le cgi-script doit renvoyer au moins un header suivit d'une ligne vide
-- ce header est soit "Content-Type", soit "Location", soit "Status"
-- il peut dans certains cas envoyer d'autres headers
-- le serveur doit verifier qu'il n'y a pas de doublons dans les headers
-- le serveur doit verifier le formatage des headers (typiquement l'encodage, par exemple pour les newlines)
-- ? comment on passe le body-message au script ? section 4.2
-	-> en ecrivant le body dans le fd temp sur lequel on a branché stdin et stdout avant d'execve le script
-- ? on doit gerer l'authentification ?
-	-> pas pour l'instant on va dire :p
-- ? pourquoi on construit un script-cgi ? section 3.3
-- ? on doit gerer l'authentification ?
-- ? pourquoi on doit construire un script-cgi ? section 3.3
-- ? si l'uri correspond au script-cgi, ca appel le script donc ? section 3.3
+#### 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
+
+#### share knowledge
+##### cgi
+- 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
