Question

Here is what I have in my .htaccess file.

RewriteEngine on

RewriteCond %{QUERY_STRING}  ^(run=[a-z0-9A-z]{13})$
RewriteRule %{QUERY_STRING}  \? [L]

All I am doing is Rewriting the QUERY_STRING for all QUERY_STRING similar to run=4f13665700694 and do nothing. A URL example: http://thinkingmonkey.me/runs/?run=4f13665700694. So, the RewriteCond should Match. But the above does not work.

But, the pattern seemed correct. Since, both preg_match & RewriteRule use PCRE - Perl Compatible Regular Expressions.

I tried it using preg_match.

$subject = "run=4f13665700694"; 
$pattern = "/^(run=[a-z0-9A-z]{13})$/";

echo preg_match($pattern, $subject);

And as excepted the above will output:

1

i.e. a successful match.

I do not understand why. What am I missing here?

Answer 1

I think it has something to do with the second line. Try changing it to:

RewriteRule ^(.*) $1?
