We're looking for a person or people to help audit MDN to find places we could speed up. Is this you or someone you know? Check out the RFP: https://mzl.la/2IHcMiE

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The delete() method of the Cache interface finds the Cache entry whose key is the request, and if found, deletes the Cache entry and returns a Promise that resolves to true. If no Cache entry is found, it returns false.


cache.delete(request,{options}).then(function(true) {
  //your cache entry has been deleted


a Promise that resolves to true if the cache entry is deleted, or false otherwise.


The Request you are looking to delete.
options Optional
An object whose properties control how matching is done in the delete operation. The available options are:
  • ignoreSearch: A Boolean that specifies whether the matching process should ignore the query string in the url.  If set to true, the ?value=bar part of http://foo.com/?value=bar would be ignored when performing a match. It defaults to false.
  • ignoreMethod: A Boolean that, when set to true, prevents matching operations from validating the Request HTTP method (normally only GET and HEAD are allowed.) It defaults to false.
  • ignoreVary: A Boolean that, when set to true, tells the matching operation not to perform VARY header matching.  In other words, if the URL matches you will get a match regardless of  whether the Response object has a VARY header. It defaults to false.
  • cacheName: A DOMString that represents a specific cache to search within. Note that this option is ignored by Cache.delete().


caches.open('v1').then(function(cache) {
  cache.delete('/images/image.png').then(function(response) {
