Subject Reproducable apache 1.3.26 /modproxy issue viewing www.kbb.com
Date Fri, 09 Aug 2002 23:32:06 GMT
Howdy,

	Overview:  The shows a blank page instead of the website.

	To Reproduce: (I'm including exact version numbers of the browser I
used, but I've seen it with other versions and different browsers as
well (ie 5.5 -blehhh) :)).

Client and Server Machine:  Redhat 7.3 x86.

Steps:
- Download, build and install, apache 1.3.26
	./configure --enable-module=most --prefix=/usr/local/apache
	make
	make install
	blah blah :)
- Configure proxy services in apache.  I have attached my httpd.conf.
- Configure Mozilla Build ID 2002051319 to use proxy.
- Flush memory cache and disk cache in browser.
- remove cache file in apache if exists - .../w/L/D/xIxiP9wnPxSezgrSfhQ
- Visit www.kbb.com with your browser
(at this point you should see .../w/L/D/xIxiP9wnPxSezgrSfhQ in the cache
and it should look good)
- once the page is done rendering do a shift 'reload' in mozilla
(which sends a Pragma: no-cache and a Cache-Control: no-cache, which
results in forcing the the cache to "revalidate")
- You should see a blank browser page
(at this point check the apache "cached file", you should see
Content-Length:0 in addition you see a "X-Cache: HIT from hostname (with
revalidation)\r\n" in a network (ethereal or other) trace.  I have
included the prefix of the proper cache file as well as a corrupted one
below).

Has anyone seen this yet?  Can others reproduce?

The information I have says that kbb.com is not akamaized, however I
didn't speak to them personally so I can't be sure how accurate that
report is.

Any help of any kind would be appreciated.

Is there anything further I need to provide?

Thanks much for your time.  Sorry for the lengthy post.

Geff

Proper cache file:

Cache file after a "revalidation" occurs from the no-cache directive:
