Question: What does the Performance Cache do? Why do all the hits in my log appear to be coming from the server's IP? Answer The Performance Cache feature in MOSXS can be used to provide a boost in speed for static content. It works by placing itself as a type of proxy in between the browser and Apache. It will keep specific types of data stored in RAM instead of having to read them off disk everytime they are requested. HTTP requests for content which it cannot or should not cache are passed onto Apache running on the same machine. In order to do it's thing, the Performance Cache must take over listening on the web server port (port 80). It then determines whether to pass on the request to Apache which is now listening on port 16080. Since Apache does all the logging, from it's perspective it is merely taking requests from anything the Performance Cache (a separate process running on the same box) gives it. Hence all hits are coming from itself.
