1439563 - Provide API access to the cache system

Status: RESOLVED DUPLICATE of bug 1435914

(WebExtensions :: Request Handling, defect)

Description

[Jason Purdy]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.167 Safari/537.36

Steps to reproduce:

I have developed an add-on called Cache Status[1] that provided an easy way for a user to clear cache as well as see what their cache usage was, in terms of disk and RAM usage. I asked on Discourse[2] if there was a way to access the cache system through the WebExtensions API, but it appears there isn't, so I'd like to request that.

Actual results:

Version 57 deprecated API access, so my module is no longer supported.


Expected results:

Some sort of new API to support clearing the cache as well as gathering information.

I'm not sure if I should make separated bug, but I hope that the solution to this bug will contain means to access cached files and provide means to download them from the cache. Access to the cached files would save bandwidth and avoid redownloading them.
