Hi,

I'm pulling my hair out with this one, so hopefully someone could =20
provide some pointers or suggestions on how to diagnose.

Using httpd: 2.2.8

Problem: mod_disk_cache is working flawlessly for vhost (a), but not =20
at all for vhost (b). The config for vhost (b) is exactly the same as =20
(a), except for the domain name, of course.

Server logs for vhost(a) show normal mod_disk_cache activity:
....
mod_disk_cache.c(1051): disk_cache: Body for URL =20
http://abc.com:80/index.php?l=3D1 cached.
....

Server logs for vhost(b) shows absolutely no activity for =20
mod_disk_cache at all.



Config for vhost (a) - which works perfectly:
---------------------------------------------

ServerName abc.com

Header unset Cache-Control
Header unset Last-Modified
Header unset Pragma
Header set Expires "access plus 1 day"
Header set Cache-Control "max-age=3D86400, public"


CacheIgnoreNoLastMod On
CacheStoreNoStore On
CacheStorePrivate On
CacheIgnoreHeaders Set-Cookie
CacheMaxExpire 86400
CacheLastModifiedFactor 10
CacheDefaultExpire 86400
CacheEnable disk /
CacheRoot /var/cache/mod_proxy
CacheDirLevels 5
CacheDirLength 4



Config for vhost (b) - only difference is Server name:
------------------------------------------------------
....
ServerName abctest.com
....



I have no idea where else to look to even begin to figure out what's going o=
n.

Any suggestions?

Thanks a million.

Regards
Henry

Do both hosts serve the same content? If both are identical, why not
just define vhost b as a serveralias in vhost a?

Thanks for the quick feedback -

abctest.com is a test environment for live abc.com, so they're
actually separate sites.

No access control on your test site?

Yes, the test site has a .htaccess file limiting access. This works
as expected.

I can browse to the test site just fine - it's just not being cached.

I suspected that.

Which is also as expected. Apache does not cache pages that are
authenticated. As you can read here:
http://httpd.apache.org/docs/2.2/mod/mod_cache.html
"content with access protection is not cached".

Ah, thanks Krist. My fault for not reading the *entire* page...
