//  This is a draft class, and may change without notice. It is disabled in

//  for it to be pushed to stable state. Use --enable-drafts to enable.

//  Create a new http request.

//  Send a request to zhttp_client.
//  Url and the request path will be concatenated.
//  This behavior is useful for url rewrite and reverse proxy.
//
//  Send also allow two user provided arguments which will be returned with the response.
//  The reason for two, is to be able to pass around the server connection when forwarding requests or both a callback function and an arg.

//  Match the path of the request.
//  Support wildcards with '%s' symbol inside the match string.
//  Matching wildcards until the next '/', '?' or '\0'.
//  On successful match the variadic arguments will be filled with the matching strings.
//  On successful match the method is modifying the url field and break it into substrings.
//  If you need to use the url, do it before matching or take a copy.
//
//  User must not free the variadic arguments as they are part of the url.
//
//  To use the percent symbol, just double it, e.g "%%something".
//
//  Example:
//  if (zhttp_request_match (request, "POST", "/send/%s/%s", &name, &id))
