um ... there are two modes of operation, one where the widget modifies 
the actual cache, and one where the cache is copied to the users session 
and changes made by the user only persist for the session.


in the WMSBrowser widget tag.

We could also add a 'MANAGESERVERS=[true|false]' but the question would 
be how to control that on a user basis ... are the users coming from a 
portal?  If yes, then I see two choices:

1. two application templates chosen based on user, one which allows 
editing and one which doesn't

2. use template replacements as in:


The value of [$bManageServers$] will be replaced with the value of 
bManageServers from the URL (get or post) request ...

(same could be done if we put in a 'manageservers=[true|false]'
