Autobahn connection via Apache mod_proxy / SSL


We have a WAMP server on a Linux backend and a Windows Server/Apache 2.4x fronting the main application. The Apache conf has this proxy…


ProxyPass "/ws" "ws://"
ProxyPassReverse "/ws" "ws://"

The Javascript call to open the connection does not using this connection parameters:

// the WAMP connection to the Router
var connection = new autobahn.Connection({
    url: "",
    realm: "realm1"

There is no request being made to the WAMP server (nothing in Chrome’s Network->WebSockets activity) and the console response is “unsupported”.

What could be the issue with this setup? Has anyone experienced a similar situation with proxy pass / SSL?

Thanks in advance.
