My setup involves using apache with mod_cache and mod_proxy to proxy and cache xml data between my iOS app and a web service. Right now I'm using awstats to see how many requests my iOS app is making to my proxy server. Is there any way to see stats (or just a number) of the requests that are actually being made to the web service's server?
Here's a diagram of the server setup for clarity:
iOS app <-----> My caching proxy server <-----> Web service
Note that I don't have access to the web service's server other than to interact with the web service.
