Re: Path to my module and APR::Socket::send() usage

[Alexander Farber]

Even though my logs show that 1 send-call usually suffices
(I have a site with 1 visitor/3 min), I've updated my script.

Not sure if returning DECLINED is a good idea.

And if you know a way to log into access_log
instead of error_log, please tell me.

Thank you
Alex
