Can i use mod_perl to filter/auth the request before forwarding the request by mod_proxy?

Hi,

I want to use mod_proxy_http(reverse proxy) to forward the permissive
requests.
can i use mod_perl to check the requests before forward them by
mod_proxy_http?


Here below are my work environment.

Apache 2.2 + Mod_perl2 + mod_proxy + mod_proxy_http

Any advice will be appreciated.

Thanks.
