Akilesh,

Your question is not clear to me, what exactly does not work when using
your proxy? Does the SSL handshake fail?

thought on this pls. reply.

Thanks,

Subject: boost::asio SSL connection thru proxy server

Hi,

I am writing a boost socket client using boost::asio to do secure HTTP
(HTTPS) communication. I Implemented my client based on the code sample
based on (
http://www.boost.org/doc/libs/1_39_0/doc/html/boost_asio/example/ssl/client.cpp

)  with little changes as I am using sync socket. My client woks fine, when
I am connecting to server directly, but I am not sure what changes I need
to make when my communication going thru proxy.

The unsecure connection(HTTP) work fine thru proxy, and here is what I do
for unsecure connection,

      1.      Initialize boost socket(IO service and other stuff).
      2.      Resolve and Connect to Proxy server.
      3.      Start writing to actual server(HTTP send request).
      4.      Start uploading/downloading.
      5.      Close Socket.

But I can’t use this above procedure for (SSL) secure connection as I need
to do handshaking with the server before I can write anything if my
understanding is correct.

Can somebody give me some pointer or code sample or step I need to do when
I am doing secure connection thru proxy server.

Just to clarify Microsoft WinInet does do (secure) HTTPS connection thru
same proxy fine. If providing my code sample I am using for SSL might help
understand the problem I can provide that.

Thanks in advance for any help.

Akhilesh Kumar
