Active Connection Establishment.This makes an active connect to the specified host. AnHTNet Object is parsed in order to handle errorsand other stuff.

Passive Connection Establishment.This function makes an accept on a port. The net must containa valid socket to accept on. If accept is OK then we duplicate thenet object and assign the accepted socket to the newly created net object.The original Net object will keep accepting connectionson the original socket, for example port 80 in the case ofHTTP. The newly created Net object will be freedwhen the protocol module has finished. If theaccepted net object pointer points to the net object itself, thatis - the same object all along - then we reuse the same Net obejct; closesthe original socket and replaces it wik the accepted one. This is a quickway of accepting a single connection.*/extern int HTDoAccept (HTNet * listen, HTNet * accept);/*.
