Detailed Description

Base Csock implementation to be used by modules.

By all means, this class should be used as a base for sockets originating from modules. It handles removing instances of itself from the module as it unloads, and simplifies use in general.

EnableReadLine is default to true in this class
MaxBuffer for readline is set to 10240, in the event this is reached the socket is closed (

ReachedMaxBuffer)

Returns: 1 to continue, 0 to abort

This may get called multiple times, for example with a chain certificate which is fairly typical with certificates from godaddy, freessl, etc. Additionally, openssl does not do any host verification, they leave that up to the you. One easy way to deal with this is to wait for SSLHandShakeFinished() and examine the peer certificate
