Currently this URL causes a 12 second slow-down when loading the edit page on extranet:

http://extranet.atlassian.com/includes/js/tiny_mce/zip_src?theme=advanced&language=en&plugins=table%2Cpaste%2Cemotions%2Cfullscreen%2Cconfluence

It is approx 300kb of content that is sent uncompressed, and sent every time (as it has the must-revalidate header):

We should fix this to serve it through the caching servlet "/s". To do this, we can't pass any parameters to the url, as by default, most browsers won't cache requests that have request parameters.

I'm raising this as a bug, as it causes severe performance penalties over slow connections. 300kb on every edit.
