Question: I'm changing my site to show friendly URLs like this:

```
www.example.com/folder/topic

```

Works fine!

But when I add a parameter to the URL:

```
www.example.com/folder/topic?page=2

```

`$_GET` stops working. It doesn't recognise the parameter at all. Am I missing something? The parameter worked fine before using full URLs.

Answer: 
If it's a mod\_rewrite problem, which it sounds like, you could add the `[QSA]` flag to your mod\_rewrite rule, to append the query string to the rewritten URL instead of throwing it away.

Your rule will end up looking like:

`RewriteRule from to [QSA]`
MrZebra's answer is the correct one. It will allow you to continue to use query string as you do at the end of a URL, and you don't have to anticipate its presence one way or the other.
