Just set disableCache to true in the options.

It is not about cache or page reload, I am still on same page. Example:
I have newsfeed that is loaded using your plugin (works perfectly). Let's presume 5 pages were loaded that way.
User fills in the form just like on facebook, all via ajax. Form passes validation and now, newsfeed loads itself using ?page=1 (ajax). But if I continue scrolling, plugin will continue from last remembered page, in this example 5.
I know I should just append that new post on top but for some other reason I cannot do that (because of applied filters, sorting etc.. it is simpler just to refresh).
Sorry for bad english.

You might need to write a sister function to clearOld that forces a cache refresh.
