That's the way it's supposed to work When a web component dispatches a request to another server Web component you are telling the server (at the end of the chain) to send to your browser (Oops! I meant Internet Client! Sorry M. Andreessen!) an HTML (or XML) response that your client will understand and your browser stays with the same URL. The same one that initiated the (possible) chain reaction in the server that resulted in said response. If, on the other hand, the response from the server is a sendRedirect, that instructs your Internet client to go to another URL and so that field changes in your browser in that case.

What Tony said... but I notice something about your URL. you've got /servlet/Logout/servlet/LoginServlet
Do you mean that every time you forward to a new servlet, you end up appending a new /servlet/xxxx onto the end of your URL appearing in the browser's address bar? Such that you have /servlet/a/servlet/b/servlet/c/servlet/d, etc, etc... ?
a similar question was posted a few weeks back. could be a path issue, check the path in your html form or your next_url and try preceding it with a / (slash) or if you alread have a slash try getting rid of it.
