URL Rewrite infinite redirects problem

Question

In my .htaccess file, I have the following line:

RewriteRule ^f/(.*)$ /blah.php?g=$1

I'm trying to make a url such as

example.com/f/three

to be interpreted as

example.com/blah.php?g=three.

However, visiting a url like the former results in a "maximum internal redirects" error. What am I doing wrong?

Answer 1

I figured out the problem. There was an additional sneaky .htaccess file inside a folder with the same name as f, which was causing all the redirects. Here is what ended up being the correct line:

RewriteRule ^f/(.*)$ /blah.php?g=$1

Since this is in a .htaccess file, the slash before the f should be absent.
