Experts,

I'm going to use this site just as a random example.

When I browse to: access.jpmorgan.com, It prepends:  
jpmalogon?TARGET=$SM$https://tssportal.jpmorgan.com/pp/pp/WSQ/servlet/appmanager/jpmaportal/jpmahome&brand=jpma

Question: What is telling the site to prepend that?
Is there a file somewhere that tells the user which "LOCATION" to go to?

That something in their web site software.  To check, I just went to that web page and I got exactly the same thing and I've never been there before.  Note that going to http://access.jpmorgan.com/ gets redirected to https://access.jpmorgan.com/jpmalogon with the rest of that query string added to it.  It's just something they have chosen to do.

It does the same for me. Once the user hits there website, it is likely just redirecting. access.jpmorgan.com is probably just a proxy front end, or, a load balancer appliance.

Hi guys, I understand that they chose to do that. I'm wondering how they do that.  Is this programmed into their VPN appliance and not editable?

Its just probably using a proxy or load balancer. Possibly even URL rewrite.

This has nothing to do with VPN.  It is a standard operation that I can do on any of my websites if I want to and there are several ways to do it.  In addition to the URL rewrite, proxy or load balancer suggested by diggisaur, I can simply write code in a server side language that will do that.

If you click on this link http://www.dibsplace.com/RWtst , you will see that I have duplicated that effect on my site.  It's part of a test page that includes re-writing URLs and detecting which one was selected.

Thank you Dave Baldwin.
The answer to my question was that the URL re-writing is hard-coded into the page.
