Re: Clustered Reverse proxy

["Sam Crawley" <mutant.nz@xxxxxxxxx>]

Thanks for the response.

That's not really going to be an issue in my case, since this cache is sitting at the back end of the application stack, and actually consists of small components that are later assembled into a complete page. The outside world never gets to access the cache directly. I could write an application to do all this of course, but it seems like most of the functionality is already there in a reverse proxy.

You're missing the fundamental point of http caching: that resources
can be cached by any agent on the wider web based on the constraints
(usually time based) of the original response. Any subsequent requests
can't affect that, for those proxies. I would guess that you'd be
better off getting your application to cache its responses to file.
