Just found that Apache::Util::unescape_uri when gets undefined value as parameter not returns undefined value, but make SUBJ! Why that's happens?
And one more question. We have well-known-2-apaches-config and when the "power" one gets SF, the "simple" returns and logs 502 Proxy error to the _virtual host_ error_log. And mod_perl-powered server logs SF to the _server_ log. Comparing time of two errors we can get request, that leads to this error. And the question is: if we have to use one mod_perl-powered Apache - how we can find request, that breaks server? (we have more than 100 virtual hosts of our customers and that will be PITA - found the error request) Gregory Belenky WebZavod (http://www.webzavod.ru) programmer
