jquery-ajax-localstorage-cache is a plugin built for jQuery (>1.5.1) and localStorage. It's a fork from the jStorage-dependent original. It provides a client-side cache AJAX responses intended to save bandwith and time.

How to use


    url: '/post',
    localCache: true,  // required to use

    cacheTTL : 1,      // in hours. Optional
    cacheKey: 'post',  // optional
    isCacheValid: function(){  // optional
        return true;

    success: function(reply) {
        // i can play with my reply ! 

On your AJAX request you got 4 new parameters :

  • localCache
    • Turn localCache on/off
    • Default: false
  • cacheTTL
    • time in hours the entry should be valid.
    • only for this specific ajax request
    • Default : 5 hours
  • cacheKey
    • CacheKey is the key that will be used to store the response in localStorage. It allow you to delete your cache easily with the localStorage.remoteItem() function.
    • Default: URL + TYPE(GET/POST) + DATA
  • isCacheValid
    • This function must return true or false. On false, the cached response is removed.
    • Default: null


  • You can delete the cache by using localStorage.clear().
  • Note that you can pre-load content with this plugin. You just have do to the same AJAX request without a success callback and the same cacheKey.
