Status: RESOLVED INVALID

(Core :: Networking: Cache, defect)

I've experienced this twice since the landing of bug 84945, but I can't of course (yet) prove that it's caused by it...

Steps to Reproduce:

1. Use Pandora.com for some time (when I experience this bug, it's after a nearly 4-hour session)
2. During that time, reload often (I usually do a shift-reload)

Actual Results:

At some yet-to-be-determined point, Pandora.com will fail to load the main .swf file, and attempts to re-fetch it via a shift-reload don't work.  Page Info says that https://www.pandora.com/radio/tuner_8_2_0_2_pandora.swf is "Not Cached"; normally, it's stored in memcache.  There are no errors in the Error Console...

The only remedy for this situation is to Clear Private Data (Cache/Authenticated Sessions; I doubt the latter is necessary); both times this occurred, I fired up Safari and Opera, and both loaded and reloaded just fine, so it doesn't _appear_ to be a network issue.

Alfred, any chance you could try to run Pandora.com in a trunk build while at work for a day, just in case you could somehow trap this?

max-age is just 60... you probably hit that, so it grabs it again.

A build ID might be nice: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9b3pre) Gecko/2008010104 Minefield/3.0b3pre.

This is invalid, as far as I can tell; I just ran into this with 2.0.0.11.

Sorry for the noise and premature semi-blame.
