Ning AHC: Secured Grizzly Websocket is not connecting through squid proxy

[manikandar]

With Grizzly provider, I could able to connect websocket through proxy.
But when I try to set SSLContext to the client, it starting throwing exception:

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

The Squid Proxy access log is showing the following request log line:
1356520015.018 0 192.168.125.1 NONE/400 3501 �e - NONE/- text/html
Note the binary data in the request line.

Notes:

1. Websocket connection through Proxy is working fine.
2. Secured Websocket connection with the same SSLContext with out any proxy is working fine.
3. Secured Websocket connection with the same SSLContext through proxy is not working.

Posted this issue in the forum and was asked to create issue for the same:
