Description

[Ian Gulliver]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.0.1) Gecko/20030119 Chimera/0.6+
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.0.1) Gecko/20030119 Chimera/0.6+

Both Chimera and Mozilla 1.3a on this platform (Jaguar 10.2.3) fail to cache
pages where the server sends Vary: Accept-Language.  For example, a page with
these headers will not be cached:

HTTP/1.1 200 OK
Date: Mon, 03 Feb 2003 19:53:27 GMT
Server: Apache/1.3.27 (Unix) mod_ssl/2.8.12 OpenSSL/0.9.6g
Vary: Accept-Language,Authorization,Accept-Encoding
Set-Cookie: logged=yes; expires=Mon, 03-Feb-03 21:53:38 GMT;
domain=ispcontrolpanel.com; secure

v2.0" l r (nz 1 vz 1 lz 1 oz 1 cz 1) "http://www.rsac.org/ratingsv01.html" l r
(n 0 s 0 v 0 l 0))
Cache-Control: max-age=86400
Transfer-Encoding: chunked
Content-Type: text/html

While a page with these headers will be:

HTTP/1.1 200 OK
Date: Mon, 03 Feb 2003 19:53:27 GMT
Server: Apache/1.3.27 (Unix) mod_ssl/2.8.12 OpenSSL/0.9.6g
Vary: Authorization,Accept-Encoding
Set-Cookie: logged=yes; expires=Mon, 03-Feb-03 21:53:38 GMT;
domain=ispcontrolpanel.com; secure
pics-label: (pics-1.1 "http://www.icra.org/ratingsv02.html" comment "ICRAonline
v2.0" l r (nz 1 vz 1 lz 1 oz 1 cz 1) "http://www.rsac.org/ratingsv01.html" l r
(n 0 s 0 v 0 l 0))
Cache-Control: max-age=86400
Transfer-Encoding: chunked
Content-Type: text/html

Both pages cache correctly in IE 6 (Win98) and Opera 6 (Jaguar).

Reproducible: Always

Steps to Reproduce:
Attempt to access a page with a Vary: Accept-Language header which would
normally be cachable.  Move to another page, and come back to the original page.
Actual Results:  
Mozilla reloads the page from the server (noticable by timing and confirmed by
server logs).

Expected Results:  
Loaded the page from local cache.
