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 127.0.0.1:11211)

OpenURI::Cache.host = ['10.1.1.10:11211', '10.1.1.11:11211']

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

Execution

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

OpenURI::Cache.enable!
# As slow a wet week
open("http://ab-c.com.au").read

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

Requirements

  • Ruby
  • MemCached
  • memcache (gem)
    • You will need to ensure that you have corresponding version of libmemcached to the memcached gem installed for installation to go by breezy
