[users@httpd] apache 2.4.1, regression, caching forward proxy configuration
Hello,
I'm using apache, instead of squid, as a caching forwarding proxy
for my intranet.
I've converted my old 2.2 configuration to 2.4, see below. The
proxy part is still working fine, but caching to disk doesn't work
anymore.
Nothing is written into the CacheRoot, no errors in the logs.
Any ideas or suggestions?
Thanks
Juergen

This slightly dated thread mentions the check-in for the realigned naming convention:
http://old.nabble.com/mod_disk_cache--%3E-mod_cache_disk-td29963400.html
I wonder if anyone confirmed Graham's work as requested?

No, there are no VHosts defined at all. See the configuration in my
initial posting.

To exclude an error in that region I've created a VHost setup
which includes the proxy and cache defines, but without success.
The problem is still the same: proxy works, caching to disk doesn't
work.
Thanks and regards

Could it be some VHost config merging thing? Cache defined in the main
server, but requests handled in some VHost? I don't have much experience
with mod_cache, but I vaguely remember some VHost config support being
added or improved in 2.4.
Double check, that your rquests are actually handled by the global
server and if not, copy or moce the cache config to the correct VHost
and retest.

Try the cache status logging added in 2.4:
http://httpd.apache.org/docs/2.4/mod/mod_cache.html#status
This worked for me in one of the older pre-release versions (2.3) but I admit I have not yet configured with 2.4.

Thanks for the hint but I've tried that already, with no result.
Even with a
LogLevel cache:trace8
LogLevel cache_disk:trace8
there's nothing in the logfile. To verify the syntax I've done the
same for the proxy module with proxy:trace8 which works, meaning a
lot of traces in the logfile.
The strange thing is that everything works with apache 2.2.x, so
my guess is that there are either new but undocumented configuration
switches or we have a regression in 2.4.1.
BTW, I've found another report for probably the same issue, see [1].
Thanks and regards

Set Loglevel to debug, or if necessary high-level trace,
for the relevant modules.
