I wanted my users to be able to go to url's like this directly

http://mvt.com/<company>/userlist.xhtml
http://mvt.com/<company>/applications.xhtml
http://mvt.com/<company>/companysettings.xhtml
etc. etc.

<company> is a variable and I need to know what the user typed in.

and when a request comes in, every page needs to load the company(since the user might have typed the url in himself).  Is there a good pattern to solve this problem in seam?  I have been hacking at this problem but most of the time have failed at coming up with a good pattern here.  It especially screws up on posts as sometimes the params are lost making url rewrites hard as there is no company as a param.  Any ideas on a good pattern to do this?

currently I have ?company=<company> and I use urlrewriter, but this is not working out so well as sometimes seam loses that parameter for some reason(and I have not been able to figure out why).
thanks,
Dean
