Data Group List use in a switch

Thanks all,

 

 

The datagroup will have various values that i want to test for in the url (i.e. a.txt, b.txt, c.txt, etc) and i want to perform actions when they are in the url.

 

I want to use a data group list so i can just remove the values from the data group list without having to alter the code.

 

 

If i cant use it within a switch statement how can i call the data group list from the if statement:

 

 

if [HTTP::uri] contains value from data group list then do stuff else do other stuff.

 

 

Thanks
