Debugging/Developing tool for apache's mod_rewrite (Rewrite Engine)

Question

Is there any tool (GUI or online) for developing and debugging apache's mod_rewrite (Rewrite Engine) rules?
Something like Regex tools that get input (for example URLs per line) and some rewrite rules; Then displays rules's output.

Answer 1

you can use rewrite log file for debugging :

<IfModule mod_rewrite.c>
    RewriteLog "/home/test/public/logs/rewrite.log"
    RewriteLogLevel 3
</IfModule>

OR you can follow this detailed debugging tutorial:
