-#### questions
-- 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 ?
