Generic function for sending http/1.1 response.
ser | TCP/TLS session object | |
method | GET/POST/HEAD | |
status_code | HTTP response code (200/401/403/404/500) | |
status_title | English equivalent to the status_code parameter | |
http_header | An ast_str object containing all headers | |
out | An ast_str object containing the body of the response | |
fd | If out is NULL, a file descriptor where the body of the response is held (otherwise -1) | |
static_content | Zero if the content is dynamically generated and should not be cached; nonzero otherwise |
HTTP content can be constructed from the argument "out", if it is not NULL; otherwise, the function will read content from FD.
This function calculates the content-length http header itself.
Both the http_header and out arguments will be freed by this function; however, if FD is open, it will remain open.

Register a URI handler.
They are sorted by length of the string, not alphabetically. Duplicate entries are not replaced, but the insertion order (using <= and not just <) makes sure that more recent insertions hide older ones. On a lookup, we just scan the list and stop at the first matching entry.
