[Zope] Site goes funny when I logout

When I logout of my site the page goes crazy ... The layout is all over the place, the images don't render etc and I can no longer use the site(links don't work) until I shut down the browser and reopen. I am running plone/zope on windows behind apache. The problem only just started after I modified the rewrite rules to be something like RewriteEngine on RewriteCond %{HTTP_HOST} ^www\.parasyn\.com.au$ RewriteRule ^/(.*) http://ip:port/VirtualHostBase/http/www.parasyn.com.au:80/corp/VirtualHo stRoot/$1 [P] Previously I did not have the rewritecond %(HTTP_HOST) in the rewrite rule, and the site worked fine, previously though I was using a different url too. ____________________________________________ Peter Millar
