[xwiki-users] outputting cache-related headers from XWiki

Hello list, as I am slowly realizing, there's no way to prevent the output of the following headers which basically say that no client or proxy caching should be done. I agree that the default policy should be to not cache but it should be possible to allow to cache. Even changing the header values with: $response.setHeader("Cache-Control","max-age=60, public") fails because it adds no-cache to the front. $reponse.setDateHeader("Expires",someDate) seems to work. This is quite odd I have to say. Should I hunt somewhere else? I fear I need to dig into the servlets. paul
