Disallow all user agents except one using .htaccess?
- by Kian Mayne
I've been struggling to get this .htaccess working. The aim is to disallow all user agents besides my app. The app sends a GET request with a user agent of lets say 'AcmeUpdater'.
Whenever I try to navigate to any file in the folder, I get a 500 - Internal Server Error.
Here are the rules I'm using:
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_USER_AGENT} !^KMUpdaterClient*
RewriteRule .* - [F,L]
</IfModule>
I have updated the .htaccess file as suggested in the answer by Nick, and restarted Apache. After trying a couple of different things, it seems that just the presence of a .htaccess is causing the 500 error. I'm getting nothing in the error logs.
The .htaccess file at the document root looks like the following:
<IfModule mod_rewrite.c>
Options +FollowSymLinks
ErrorDocument 404 /index.php?error=404
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
</IfModule>
So I realised that the error logs were in chronological order rather than the reverse chronological I expected (Oops!).
The error I'm getting is: </IfModule> without matching <IfModule> section. I removed the </IfModule> and still I get that error. Ideas?
