Linking from intranet to third party page

If I have a link from an intranet (i.e. web pages only visible from inside our LAN or over a VPN), will the receiving page be able to see details (server, internal url, session variables, post, get vars etc) of the page calling it?

As far as I am aware, the only detail the recieving page will gather is the referring URL address.

if your calling it from out side, it won't even load.

if you call it from inside you won't be able to get that info just from a url, you would have had to make a page display that info.

OK I suppose I will have to test it.

@nplib, I'm not sure what you mean?

Hi there, I have just tested this with both the $_SERVER['HTTP_REFERER'] and setting a session on the intranet server and trying to read it on the remote server.

The results were as follows:

1. The remote server DID receive the referrer i.e. I made it echo http://localhost/test.php
2. The remote server DID NOT receive the session variable.

This is OK, but it still appears to be important to mask any essential information from the referring page.
