Web sockets

Description

When using web-sockets the following error occurs:

WebSocket connection to 'xxx' failed: Compressed bit must be 0 if no negotiated deflate-frame extension

As we have noticed it happens as a result of several "server pushes" made via WServer::post (or most likely when the triggerUpdates() is called afterwards). It doesn't happen instantly, but rather after a certain time or may be a certain number of Server Pushes. Not much of a regularity that we have noticed, but it happens always (!). Can be cured only with a full app reload (termination).

It happens with Chrome, FF, IE so it cannot be a result of a single browser's protocol misinterpretation.

Hey,

With what version of Wt do you get this? I believe this problem has been fixed in 3.3.0, or cerainly in latest git.

At least, we haven't seen it happening anymore lately.

Hi, Koen,

thanks for a prompt reply.

Meanwhile we have rebuilt our app with the latest version of Wt from your GIT repository and it has failed again with the same error.

Then we followed your request to enable the HTTP tracing and here's what we got (sorry there's a bit of a mess because it happened to be an application restart due to an F5, so only the second session matters):

Possibly the error happened at the line shown with bold. Hope it helps you.

Thanks.

Hey,

I've pushed a new version just now. I would appreciate if you could give it a test.

If I'm right (and the patch is good) then I would expect that the error above is a consequence of the problem, not a cause.

Hi, Koen.

It works fine now. Thanks a lot for a very quick fix.

To be honest we didn't expect you to react so promptly.

Thank you.
