int  status_code,
const char *  status_title,
struct ast_str http_header,
struct ast_str out,
const int  fd,
unsigned int  static_content 
)

Generic function for sending http/1.1 response.

Parameters:
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
Note:
Function determines the HTTP response header from status_code, status_header, and http_header.
Extra HTTP headers MUST be present only in the http_header argument. The argument "out" should contain only content of the response (no headers!).

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.

int ast_http_uri_link ( struct ast_http_uri urih  ) 

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.
