66482 - Implement memory cache usage for HTTP

Status: RESOLVED FIXED

(Core :: Networking: Cache, defect)

Description

[Jens Lautenbacher]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.16-22 i586; en-US; m18) Gecko/20010122
BuildID:    2001012208

when looking at the cache statistics via about:cache, the memory 
cache usage always seems to be zarro (despite activating it in the debug pref,
of course)

Reproducible: Always
Steps to Reproduce:
about:cache in the location bar :-)

Currently, the memory cache is not used by HTTP. It is only used by IMAP.

Marking NEW and making a RFE

Comment 3

[Ben Bucksch (:BenB)]

Wow.

This is not an enhancement, but major base requirement. I always disable disk
cache, because I have enough RAM and don't like frequent disk accesses. I didn't
know until now that this caused Mozilla to always go to the net (a local proxy
in my case). Major perf bug. I'm pretty sure I'm not the only one, who assumed
that the memory cache size perf in the UI would apply to HTTP. This is also a
major 4x parity.

Would this speed up Mozilla?

Comment 5

[gordon]

Yes, it will speed up HTTP, especially for https, which must not be cached 
persistently.  This is currently planned for the mozilla 0.9 release.

Comment 6

[gordon]

This fix is on the DISKCACHE2_BRANCH, but we we're ready to land that for 0.9.  
Changing target milestone to 0.9.1.

This fix is now on the trunk.
