Server Caching

This page discusses a number of issues surrounding caching of (HTTP) data locally on school servers.

Immediate questions

Software to use for caching. The current possibilities are

• Lighttpd [http://www.lighttpd.net/}
• Polipo [1]

Short Term Questions about Use cases

Caching use case

Caching materials after viewing

• One laptop caches locally, both in memory and on disk (in case of failure?)
• A set of laptops sharing a cache that's too large for any individually
• A server caching and aggregating caches from individual machines -- can it uptake cached materials if a connecting laptop has something in its cache that's not on the server?

Queuing requests

• A laptop requests something from a local cache;
• A cluster of laptops listens to requests from individual laptops in the cluster;
• A server listens to requests from connected laptops (directly, or passed on from others not currently on the mesh)

Caching requests without viewing

• A laptop passes on a request, a server picks it up while the laptop is off-mesh and caches the result

  Some sort of notification or syndication of the incoming material
