Yes, everything after `?` is treated as query parameter from current code,
see server_http.c:

   373                          query = strchr(desc->http_path, '?');
   374                          if (query != NULL) {
   375                                  *query++ = '\0';
   376  
   377                                  if ((desc->http_query = strdup(query)) == NULL)
   378                                          goto fail;
   379                          }

But RFC 3986 allows to use ';' as separator as well, probably it need to be
fixed.

Anyway, I not sure that matching by GET parameters in locaiton is good idea.
