Well, I thought that too, but couldn't get a grip on it. Picture the situation I described before. Whenever a page is served outside it's template, a logmessage is generated. Now when I see a page without template on my screen (wrong) and I look in the logfile I see that only the allowed address is written as being served. That's why I thought there was some optimisation in the cache engine that limited the number of equal requests to the backend to one for each URI. This would then even go beyond any headers, but more on the principle of 'the page served at exactly the same moment is the same page'...? --Frank PS: I now removed the caching mechanism from the setup and everything is working fine through the proxy. Whenever I cross this bridge again I will start looking more closely.
