 ## work together
 
+#### 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 field duplicate (resolve conflicts)
+->	TODO : if status field, change server status for this one
+!	TODO : there is no space between filed name and ":"
+!	TODO : if no Location field && no Status field -> status code = 200
+!	TODO?: handle Location field, either :
+			- local : start with '/' --> rerun the request with new uri
+			- client : start with '<scheme>:' --> send back status code 302
+
+#### what cgi ?
+- a basic form with "name" and "something", that return a html page with that
+- a script called by a file extension in URI
+
 #### 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 ?
