Apache: Where to examine the redirection logs?

Question

I have complicated RewriteCond and RewriteRule in one machine. And according to these rules, some of the requests will be redirected to another machine.

So is there any Apache log that shows clearly how the redirection takes place? Because the redirection is happening in the ways that I don't anticipate.

Answer 1

For the uninitiated, this is how you should write your *.conf file:

  NameVirtualHost *:80
  <VirtualHost *:80 >
    ServerName gw.myserver.net
    DocumentRoot "C:\Program Files\MyCompany\myserver\Web"
    DirectoryIndex index.html index.php
    RewriteLog "logs\rewritelog.txt"
    RewriteLogLevel 3
    <Directory  "C:\Program Files\ MyCompany\ myserver\Web">
       AddDefaultCharset UTF-8
       Order Deny,Allow
       Allow from all

       RewriteEngine on
       RewriteBase /
       RewriteCond %{HTTP_HOST}   ^gw\. myserver\.net$
       RewriteRule !^(login|index.php)  http://pmmenu. myserver\.net%{REQUEST_URI}$1 [L,R=301]
       # we check if the .html version is here (caching)
       RewriteRule ^$ index.html [QSA]
       RewriteRule ^([^.]+)$ $1.html [QSA]
       RewriteCond %{REQUEST_FILENAME} !-f

       # no, so we redirect to our front web controller
       RewriteRule ^(.*)$ index.php [QSA,L]
    </Directory>
  </VirtualHost>

Answer 2

You need to enable the rewrite log in your virtual host or server config

RewriteLog "/usr/local/var/apache/logs/rewrite.log"

see http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewritelog

Answer 3

You can configure a logfile specifically for Rewrite processing with the RewriteLog directive. The amount of logging can be selected with RewriteLogLevel.
