Subject: [PATCH] add no-cache Pragma and Cache-control headers to the http
 response.. I see no reason why not to do this as nothing in Mir should be
 cached and I have been annoyed to many times by opera and IE caching stuff
 not to do this. It has to be in the http headers and not in the Meta tags as
 some browsers have problems..
