There are three ways to remove objects from the Varnish Cache :
- Clear the cache by a particular url.
- Clearing the entire cache.
- Fine tuned control of the cache with Varnish Cache ban expressions.
Clear a particular URL
You can remove particular URLs from the cache by entering the URL and clicking Purge.
This form accepts wildcards in the form of
*, so entering
/images* will purge all URLs starting with
/images. You can also clear the cache for a specific URL, for example
Empty the entire cache
This will remove everything from the cache. Use this if the cache is completely out of date and it needs to be refreshed.
NOTE: This may cause increased load on your origin server and also slow down your website for users until we are able to refill the cache.
Varnish Cache ban expressions
You can think of bans as a way to purge or filter out object that are already in the cache. Keep in mind that this method does not ban future requests from being stored in the cache.
Support for bans are built into Varnish Cache so to learn how to use bans, see the Varnish Cache documentation.
