# Miva - Use Transient Module to Cache Entire Store (prototype)
The following code is a basic prototype of how the main landing pages could be cached using the [Transient module](http://apps.miva.com/transients.html) and some .htaccess rules.

So far it only would work well with Miva's Long Merchant URLs or the Legacy SEO Short Link structure. I haven't tried finding a way to get it to work with URI Management yet.

This implimentation is not complete, and would require some other updates:

- Remove Session IDs from the cached HTML
- Use to AJAX load in mini-basket & account info
- Needs to account for query string parameters, POST's, and other more intricate web-requests
- Add a way for store-owner to purge the cache manually.
- Test this thouroughly!
