Question

I’m trying to build a PHP server(i’ll call it here server1) , that works as a middle server between another web server (server2) and clients.

The reason I’m doing that, I want to hide the API Key I’m using to access the server2 from server1. Also, I want to decrease number of calls to server2.

My question is, How can I do something that caches the calls from server1 to server2? Is there a module or something to use in PHP? I don’t want each call from the clients to produce a call to server2.

another requirement is to cache the feeds from server2 for 5 minutes only.
