xCache

Rails cache helper. Binds to models, invalidates on object update and helps vith etag cacheing

Models would idealy have updated_at field. If they have it, update invalidates cache, automaticly.

If there is no updated_at fields invalidate with calling @object.xcache

Example

Examples say it all

Full HAML example, view

- xcache @product do
	foo

- xcache @product :list_item do
	foo

In controller for cache invalidation

@product.xcache # clears cache for object

In controller for fresh_when helper

return if xcache @product, @user, @foo, ....

Send list of objects. plugin finds last updated time, checks browser cache time and serves from browser cache unless modfied http://www.checkupdown.com/status/E304.html

How many functions I have to remember? Just 1, there is one function "xcache" to dominate all usage

• in template replaces cache tag
• as model instance method, clears model cache
• as controller method helps with rails fresh_when method
