Cache web pages for 5 minutes

[MaHuJa]

Imagine a user auto-reloading a page on another screen every 1 seconds to see if his kill was successful etc.

• When asked for a page check for a copy in cache.
• If it is older than 5 minutes, discard it. Else build it
• Send the cached copy of the file.

For debugging purposes we should be using other mechanisms like direct queries or flushing the cache.
