Function ap_matches_request_vhost

server/vhost.c:953–991

Suppose a request came in on the same socket as this r, and included * a header "Host: host:port", would it map to r->server? It's more * than just that though. When we do the normal matches for each request * we don't even bother considering Host: etc on non-namevirtualhosts, * we just call it a match. But here we require the host:port to match * the ServerName and/or ServerAliases. */
