Yeah, but that's the problem running repoquery -f 
/usr/lib64/httpd/modules/mod_proxy.so does not give any output.

rpm is actual package manage working under yum, so it job is to maintain 
the installed package, but I would expect repoquery (which's a part of 
yum and as the name suggests 'query the repository') to do the same for 
all added repositories, cause rpm is not responsible for that. And 
actually it does do that using the downloaded repodata (as you already 
know), but problem is it's no working all the time.

For e.g. it works here --

repoquery -f /etc/htt\*
