197904 - Use a custom directory service key for cache instead of NS_APP_USER_PROFILE_50_DIR

Status: RESOLVED WONTFIX

(Core :: Networking: Cache, defect)

Description

[Conrad Carlen (not reading bugmail)]

Certain applications want to keep the disk cache in a location which is outside
the profile dirrectory. They should be able to do this by re-defining a
directory service key. That isn't possible right now because cache just asks for
NS_APP_USER_PROFILE_50_DIR and then appends "Cache" to it. The proposal is:
Define a key called NS_APP_CACHE_PARENT_DIR which, as its name says, returns the
parent of the disk cache. The cache service will still be responsible for
creating the cache directory.

Note that we need to implement a locking mechanism for the Cache dir too.

dupe/depend to bug 74085 ?

Filed bug 197946.

Bug 74085 could depend on this. If we have a directory service provider
determine the location of the cache, we could put the logic there to make sure
that it defaults to a *local* directory.
