[squid-users] Squid Websocket Issue

[Eliezer Croitoru]

I can give a hint that once you see the request you can identify using an ICAP\ECAP services couple details about the request.
Basically I had a regex which allowed any what's app traffic to be spliced by the SNI domain name.
It should be something like "w[0-9]+\.web\.whatsapp\.com$" to match the required domains for whatsapp to be spliced.
If nobody will try it before me it's on my todo list for this release (3.5.23, 4.0.17).

You are the first person to ask about WhatsApp traffic.

These might be a useful starting point
<http://wiki.squid-cache.org/Features/SslPeekAndSplice#Configuration_Examples>

What the examples are doing for banks is what you want to do for WhatsApp.

The trick though will be figuring out how to splice *before* seeing what type of HTTP request exists inside the tunnel. If you are lucky the app will be using SNI.
