I'm trying to forward example.com/signup and example.com/signup/ (with trailing slash) to example.com/signup.php

I wrote following to .htaccess and it works for example.com/signup/ but doesn't work without trailing slash... How can I solve the problem?

```
RewriteEngine On
RewriteRule ^question/(.*)-(.*) /question.php?qid=$1
RewriteRule ^signup/ /signup.php

```
