All,

I'm running some load tests in a dev environment, and I'm seeing acess
log messages like these:

::1 - - [21/Apr/2014:14:15:03 +0000] "OPTIONS * HTTP/1.0" 200 - "-"
"Apache/2.4.9 (Amazon) OpenSSL/1.0.1g-fips PHP/5.5.10 mod_jk/1.2.40
(internal dummy connection)"

Paired with mod_jk errors like these:

[Mon Apr 21 14:15:03.359 2014] [23925:3072505728] [warn]
map_uri_to_worker_ext::jk_uri_worker_map.c (1096): Uri * is invalid.
Uri must start with /

This happens to be running Apache httpd 2.4.9 with mod_jk 1.2.40, but
I can see similar messages in an otherwise identically-configured
server running httpd 2.2.23 and mod_jk 1.2.37:

==> access.log <==
::1 - - [21/Apr/2014:14:20:24 +0000] "OPTIONS * HTTP/1.0" 200 - "-"
"Apache/2 (internal dummy connection)"

==> mod_jk.log <==
[Mon Apr 21 14:20:24.159 2014] [12384:3072042880] [warn]
map_uri_to_worker_ext::jk_uri_worker_map.c (1057): Uri * is invalid.
Uri must start with /

In my httpd 2.4 environment, I seem to be seeing them much more
regularly (once every second or two) than in my httpd 2.2 environment
 (maybe every minute or two). If possible, I'd like to minimize the
amount of stuff that goes into my mod_jk.log file, and since this is
logged at the WARN level, it's tough to justify disabling it.

Now, I realize that the OPTIONS * messages are httpd's internal
monitoring queries to see if workers are serviceable, so that's not my
question. My question is why mod_jk complains about them. Perhaps a
URI of "*" itself is invalid, but since httpd is known to issue
internal queries like this, why doesn't mod_jk simply ignore them?

Thanks,
- -chris
