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.
