[FX.php List] Different REMOTE IP each screen

[Jonathan Schwartz]

Roger,

Yes, it goes back to AOL.  example IP is : 207.200.116.197

So I guess that the answer is proxy servers.

It's not like this wrinkle does a lot of harm.  I have been capturing 
the remote IP address in a FileMaker log in order to problem solve 
when a user reports problems.  I can still see the thread by using 
the first three number blocks in the IP.  In addition, if the user 
has successfully created a session, I can use the SID as well.

Just wanted to know what was going on.

Thanks

J
