htaccess rewrite rule returns internal server error

Question

I'm trying to learn how to rewrite URLs on my website, and I've followed several tutorials and read through the questions on here, but I keep getting an internal server error. I want to redirect user.php?u=$log_username to juster example.com/$log_username. I commented out each line, and only the the last line generates the error. This is what I have now:

RewriteEngine On
RewriteBase /
Rewrite Rule ^[A-Za-z0-9]+/?$ user.php?u=$1 [R=301,L]

Answer 1

You have a syntax problem in your rule. Instead of Rewrite Rule you need RewriteRule :

RewriteEngine On
RewriteBase /
RewriteRule ^([A-Za-z0-9]+)/?$ user.php?u=$1 [QSA,L]

You also needed to capture the URI in a group.
