# Cache Policy

### <mark style="color:green;">What is Cache Policy?</mark>

By defining cache policy, you can determine how an application should handle caching of data on the forward and backward navigations.&#x20;

Caching stores a copy of frequently accessed data/page locally on the device to improve performance and reduce the need to fetch the same data from a remote server repeatedly.

### <mark style="color:green;">How to setup Cache Policy?</mark>

**1.)** Go to Add-ons -> Extensions -> Cache Policy.

<mark style="color:red;">**NOTE:**</mark> <mark style="color:red;">Please create a new version of the App e.x. 1.0.2, if the current version does not support this feature. If the previous version is live on the stores, then request a new build and submit this new version to the stores.</mark>

**2.)** Select from the 3 different strategies:

* **Default mode:** No data/page will be cached in this strategy. If user will login to the app then it won’t store any session data.
* **No Cache Policy:** Backward navigation will be cached but new page navigation will be always from the network.
* **Cache else Network:** This strategy uses cached resources from both backward and new navigation when they are available and not expired, otherwise it will load resources from the network.\
  **Note**: App cache expiration is based on your website's cache expiration time.
