Helps in overriding cache policy

What is Super-Cache?
Super-Cache is an effective Chrome extension designed to control caching behaviour on the client side. It empowers users to override caching policies set by the server. The tool is highly useful in that it ensures all requests from the selected host are cached, along with static content that originates from different hosts. This is particularly useful for linked external scripts and sites on different domains, where the extension applies the same caching behaviour.

UPDATE: Bugs fixed as reported by M-Ubaid Raza, thanks for informing.


  1. Override caching policy that has been set on the server. Select a host on which the caching is required and all requests from a page with that host will be cached.
  2. Caching of static content which are on a different host will also be cahed (read Note for further explanation)

Note: say you have a site on which you have set a caching policy thru the extension. Now if the any page on links to external scripts and sites which are on a different domain such as or, the extension will automatically apply the same caching behavior as that of

Unfortunitely it works only in my 2 years old chromium, not in the 2019 chome. And unfortunitely i can not cache the "mainframe". Only 3 positions to cache, instead of 4 positions. But when it works, it works wonderful. Youtube and Stream-Websites starts much faster. Therefore i need a update !!
