 ## work together
 
+#### 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 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

 #### questions
