tcpip

Hello, To keep things simple, please allow the "assumption" that some code requires the use of a full URL, even though the domain is on the same server, i.e. a simple file path cannot be used.

TCP/IP?? Question: If a form action target = "http://this-full-URL.com/postdata" (for example) and that URL is also on the same server, then which happens first?

A) Data is sent "out onto the web", and then returns to the same server, or

B) Before sending any (possibly sensitive) data, the server (Linux, Apache, PHP), first "discovers" the target address is local, so (clearly) no data is sent over the net? Thank you.
