Member Function Documentation

void HttpDebugSocket::Init ( ) [virtual]

Called by ListenSocket after accept but before socket is added to handler.

CTcpSocket uses this to create its ICrypt member variable. The ICrypt member variable is created by a virtual method, therefore it can't be called directly from the CTcpSocket constructor. Also used to determine if incoming HTTP connection is normal (port 80) or ssl (port 443).

Reimplemented from Socket.

void HttpDebugSocket::OnFirst ( ) [virtual]

Callback executes when first line has been received.

GetMethod, GetUrl/GetUri, and GetHttpVersion are valid when this callback is executed.
