444345 - unable to display PDF delivered via SSL with cache-control:private since Firefox 3.0b2

Status: RESOLVED INCOMPLETE

(Core :: Networking: HTTP, defect)

Description

[Adam Hauner]

We had problems on intranet web application with displaying PDF files in Firefox 2.0.0.10 and lated. Those files were delivered to users via SSL with cache-control:public. I filled bug 420310 for it. Boris found, that cause is in creating plugin cache files (see bug 420310, from comment 14).

In the same time displaying in trunk version of Firefox 3.0 was okay.

We tweaked our web application in last month and PDF files delivered via SSL have now cache-control:private. Boom! They can't be displayed in Firefox 3.0 final with default setting of browser.cache.disk_cache_ssl (false). Plugtmp directory is created, but any plugtmp-X file is not present in it.

If browser.cache.disk_cache_ssl property is set to true, PDF are displayed (plugtmp directory is not created, any plugtmp-X file is not present).

Regression occurred between Firefox/3.0b1 (2007110904) and Firefox/3.0b2 (2007121120), so maybe it regressed from one of bug 402649, bug 402460, bug 262116 or bug 345181 (noted in bug 420310 as maybe related bugs on trunk).

I could try find smaller regression windows or provide HTTP Mozilla log, if somebody need it.

Testcase works fine in Firefox 3.0.3.
