One thing that comes to mind is that Firefox might be caching some resources while IE is not caching them, and so repeatedly fetching something. This difference might not show up when the server is local, but be much more significant when the server is remote and more heavily loaded. I suggest you enable logging of all requests on your server and then compare the list of URLs fetched by firefox with the list of URLs fetched by IE for the same page. This can be done on your "local" server, not the remote one. I would also enable the "live headers" plugin in firefox and have a look at the http headers for pages, making sure that they have the appropriate caching headers set. Regards, Simon
