Lighttpd

Hi..

lighttpd version 1.4.26.

mod_proxy does not forward response until socket connection is closed with host proxy (it simply caches the data).

I did a fix but 'm not very sure how much generalized/stable it is (it is working fine in my scenario).

Please have a look at it & if the fix seems fine then a patch can be released.
The file is attached for reference.

//Check for Content-Length tag & data received is equal to Content-Length
if((con->parsed_response & HTTP_CONTENT_LENGTH) && (con->response.content_length == blen))

                        return HANDLER_GO_ON ;
                else
                        /* waiting for a response */
