500 Internal Server Error with RewriteRule，从旧目录重定向到新目录

Question

I'm sorry, I know there are a million mod_rewrite questions on here already. I looked through a good many and tried to learn from others' mistakes, but I don't see what I'm doing wrong here.

My site used to be at http://example.com/andrew/qa . Now it's at http://example.com/fdso .

I just want to redirect all /andrew/qa/(.*) URLs to /fdso/$1 . Including changing the URL on the browser, which I understand the 301 option takes care of:

DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/andrew/qa/.* [NC]
RewriteRule ^/andrew/qa/(.*)$ /fdso/$1 [L,301]
</IfModule>

I have this in a .htaccess file at /andrew/qa/.htaccess.

I'm getting a 500 Internal Server Error and can't figure out why.

And the server I'm on does not seem to generate logs for some reason. (The logs directory is missing.) I have very little control over this server, as I don't have root access.

This line is causing 500 error:

RewriteRule ^/andrew/qa/(.*)$ /fdso/$1 [L,301]

It is because 301 should be R=301 .

However your rule will still not redirect because of a leading / and presence of /andrew/qa/ in RewriteRule pattern.

Have it this way in /andrew/qa/.htaccess :

RewriteEngine On

RewriteRule ^(.*)$ /fdso/$1 [L,NE,R=301]

You also don't need redundant RewriteCond .
