Re: [xSocket-develop] xsocket ssl through proxy problem

[Gregor R. <gre...@go...>]

Hi Grant,

this seems to be a bug. I supposes xSocket interprets the http connection as
'non persistent' by receiving the CONNECT response. This could be the reason
why the connection is disconnected.

Please file the bug

Thanks
Gregor
