High cache storage usage on client browser

Today when I was checking my content settings on Chrome ( chrome://settings/content/all ), I noticed that a large portion of my local data storage come from discourse sites:

And I barely visit these sites, at most twice or thrice.
(There is another which uses 1GB+ that I have already deleted before I screenshot.)

From the detail, most of them are “Cache storage”.

I’m not sure if it’s normal, but I think this should be addressed/improved. Using this much cache for a site that users don’t frequent doesn’t sound ideal.

This is a known behaviour of Chrome - please see this topic for more information:


Thank you for the quick reply.
