20201 - Reload not working properly (at least through proxy)

Status: VERIFIED DUPLICATE of bug 14772

(Core :: Networking, defect, P3)

Description

[Biswapesh Chatterjee]

System: WinNT SP5 on PII 400 with 64 MB RAM.
Build: Mozilla 1999112508.

Overview: Reload is not working properly (at least through proxy). Pressing the
<Reload> button fetches the document from the proxy cache instead of directly
from the server.

Test Case: Open Mozilla, NS4.x, IE5 from the same machine. Set them up so that
they pass through a proxy. Set proxy access loggin on. Load http://mozilla.org
in all three windows. Now press <Reload> in all three and monitor the proxy
access log. This is what you get:

From Mozilla 1999112508:
-------------------------
943883898.617     23 172.18.16.56 TCP_HIT/200 10824 GET
http://www.mozilla.org/ - NONE/- text/html

From IE5:
----------
943883995.990   2305 172.18.16.56 TCP_MISS/304 137 GET http://www.mozilla.org/ -
 DIRECT/www.mozilla.org -
943883998.840   2802 172.18.16.56 TCP_MISS/304 137 GET
http://www.mozilla.org/images/mozilla-banner.gif - DIRECT/www.mozilla.org -

From NS4.7:
------------
943884085.187   2450 172.18.16.56 TCP_MISS/304 137 GET http://www.mozilla.org/ -
 DIRECT/www.mozilla.org -
943884088.668   3479 172.18.16.56 TCP_MISS/304 178 GET
http://www.mozilla.org/images/mozilla-banner.gif - DIRECT/www.mozilla.org -

So, Mozilla is loading the document from the proxy cache while the others are
requesting direct transfer from the server (correctly, since <Reload> should
fetch from the server directly and not from the cache).

Proxy Used for testing: Squid 2.0Patch2 on AIX (compiled from source).

I am getting some strange behaviour - it seems to work at times. But the bug is
definitely there since updating a page in my site and hitting <Reload> from
Mozilla is getting the old page. Again, all this through proxy. Apropos of
this, another small bug - the network preference in all.js for do-not-use-proxy-
for does not work. Filing another bug for this.

Reassigning all of leger's unscreened Browser-General bugs to [e-mail]
for pre-screening and triage.

Moving to "Networking" Component from "Browser-General"

[e-mail], I've read 30+ bug reports looking for one that this is
a DUP of, but no other bug report involves both proxies and reloads...
this looks like a new issue.

Depends on hooking up the buttons to pass the right load flags.

Cache needs to set "Pragma: no-cache" on the outbound request for clean reloads.
assigning to cache men.

This depends on a m15 bug( 21137) being fixed. Do we need to fix that one for 
beta also?

Comment 8

[Gagan]

more like a depends on instead of dup but with 14772 fixed this will be too. 
Marking as dup...
