Check For Module Presence in .htaccess

By  on  

One of my favorite Apache modules is mod_rewrite. mod_rewrite allows me to manipulate page URLs so that I can search engine friendly URLs. Not every Apache server has the mod_rewrite module installed so you will want to add a conditional statement within your .htaccess file to make sure it's there.

The .htaccess

#Wordpress's .htaccess code
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

If the "mod_rewrite.c" module is present, that means that mod_rewrite is available and will be used. If not, the mod_rewrite code will be ignored. Using this conditional statement will prevent 500 Internal Server Errors.

    So what is the fallback for when it is not available? If you do this you need to make sure your code has a way to handle it, especially if your mod_rewrite conditions are passing get vars.

    I personally would like to know about a 500 server error so that I could fix the problem.

    Would it be fine to include this code into httpd.conf itself?
    Or is that a bad idea?

    Thanks David.

    Nope, the answer is it is bad idea because, Rewrite Base is only valid per-directory config files.

    :D
