OpenURI with caching

Carelessly make OpenURI requests without getting hate mail.

Running with MemCached

Require the library

require 'openuri/memcached'

Start memcached server

ben@Spinners ~/ Ϟ memcached -d

Set your memcached host/s (defaults to = ['', '']

The default expiry is 15 minutes, this can be changed using the expiry method

# Ten long minutes
OpenURI::Cache.expiry = 600

Running using Rails cache

You can also cache your OpenURI calls using Rails cache. require the library using require openuri/rails-cache


Use exactly the same as you would OpenURI, only.. enable it.

# As slow a wet week

Quit your app (leave memcached running) and re-run the same request, It will come from cache.
