Content-Length response header is permitted by the RFCs, but not necessary with HTTP status 101 Switching Protocols. x-ref: "websocket proxy fails if 101 Switching Protocols from backend includes Content-Length" https://redmine.lighttpd.net/issues/3063 Signed-off-by: Glenn Strauss --- src/http-header-glue.c | 1 + 1 file changed, 1 insertion(+) --- a/src/http-header-glue.c +++ b/src/http-header-glue.c @@ -961,6 +961,7 @@ void http_response_upgrade_read_body_unk (FDEVENT_STREAM_RESPONSE_BUFMIN | FDEVENT_STREAM_RESPONSE); r->conf.stream_request_body |= FDEVENT_STREAM_REQUEST_POLLIN; r->reqbody_length = -2; + r->resp_body_scratchpad = -1; r->keep_alive = 0; }
