[mod-security-users] How to log transformed REQUEST_URI/​REQUEST_URI_RAW?

[Web C. <we...@we...>]

Hello together :)

How can I find the reason why the rule below was triggered? It looks like
the audit log does not provide enough information in this case either.

%{REQUEST_URI}         gives me: /yyyyy.php?site=http://blubb
%{REQUEST_URI_RAW} gives me: /yyyyy.php?site=http://blubb

I think the transformed REQUEST_URI might be something like
"/yyyyy.php?site=http:/blubb" without the double slash. I want to be sure
why the rule was triggered and I want to see it black on white for
certainty. How would you do it?

ModSecurity version: 2.9.4
Apache Version: 2.4.48

Rule / in httpd.conf
------------------
# Make sure there are no URI evasion attempts
SecRule REQUEST_URI "!@streq %{REQUEST_URI_RAW}" \
    "id:11000,phase:1,deny,t:normalizePathWin,log,\
    msg:'URI evasion attempt REQUEST_URI: %{REQUEST_URI} REQUEST_URI_RAW:
%{REQUEST_URI_RAW}'"

error.log
------------------
[yyyy-mm-dd hh:mm:ss.mmmmmm] [-:error] 127.0.0.1:35220
