blocking variables

[fishingfriend]

How can I block:

/index.php?app=abc

but not

/index.php

Is there a way of blocking anything with *app*

thanks...

Welcome. Glad to have you aboard. I believe you can do

/index.php?app*

But I'm not a technical person. You may also want to look at:
1. [w3.org ]
2. [webmasterworld.com ]
3. [webmasterworld.com ]
