-/**
- * This function is responsible for opening up the connection to the remote

- * function will NOT receive anything from the server, however. This is in
- * contrast to previous incarnations of 'httpOpen'.
- *
- * The reason for the change is due to one small fact: some requests require
- * data to be sent in addition to the header (POST requests) and there is no
- * way for this function to get that data. This function is called in the
- * slotPut() or slotGet() functions which, in turn, are called (indirectly) as
- * a result of a TDEIOJob::put() or TDEIOJob::get(). It is those latter functions
- * which are responsible for starting up this ioslave in the first place.
- * This means that 'httpOpen' is called (essentially) as soon as the ioslave
- * is created -- BEFORE any data gets to this slave.
- *
- * The basic process now is this:
- *
- * 1) Open up the socket and port
- * 2) Format our request/header
- * 3) Send the header to the remote server
