I have a configuration where my Seaside application (a Pier 2 website) is 
available in the root 
context. I use apache as a proxy to forward the requests to Seaside. Something 
like this:

    RewriteEngine On
    RewriteRule ^/files/ - [last]
    RewriteRule ^/(.*)$ http://localhost:9093/myapp/$1 [proxy,last]

In Seaside I added the following preference:

    application preferenceAt: #serverPath put: '/'

Everything works fine most of the time. Except when the session has expired. 
When the users 
clicks on a link http://host/page?_s=xyz he is redirected to 
http://host/myapp/page. And of 
course this page doesn't exist.

Any ideas how this can be fixed?
