Status: RESOLVED WORKSFORME

Description

[Fischer [:Fischer]]

For the new Storage API standard [1] and the Storage management [2], Need API to remove HTTP cache per origin to let user remove site data of selected origin.
However, currently no such API in [3].

Hi Francis,

It looks like we need,
1. The Http Cache team to help with the API
2. Discuss how to approach this on the Storage management project v1 schedule.

Thanks

Junior, could you provide some suggestions?  Thanks.

With some discussion with :schien, we can try nsICacheStorage::asyncDoomURI to evict the http cache.
Since asyncDoomURI is based on kinda exact matching without ref, you may need |asyncVisitStorage| to traversal all the cache and check if the cache is of the same schemeless origin group.

I have nothing to do with project schedule, so pass the ni back

Successfully using nsICacheStorage::asyncVisitStorage to enum caches and pick out target caches.
And then remove target caches using nsICacheStorage::asyncDoomURI.
