So the basic usage of cache is shown by @mingos. He talks about generic cache, which is good. However, ZF has few different cache mechanisms that you can use for different things. You don't need to limit yourself for one type of cache. You can use a mixture of them. For example, for caching your static content Zend_Cache_Frontend_Page would be worth considering as it would generate a full html file of your static pages. If you have lots of config files, e.g. long routes.ini or whatever, you can cache them using Zend_Cache_Frontend_File. With this you would save time parsing the ini files for every request. Significant parts of your views could be cached using Zend_Cache_Frontend_Output, etc.

What to cache and when to update a cache is a tricky question. It all depends on how fast and how often your content is changing. For example, if you have like 100 new comments per second, there is no point in cleaning your comment cache 100 times per second (i.e. for each new comment). It would be better maybe to have comments for each post cached separately from the comments of other posts. Then you would clean/refresh a cache associated with only this post.
