Hi Sumod,
You can use matchclass to check whether a client IP is part of an address type datagroup. And you can also use matchclass to see if the requested URI is part of a string datagroup. [IP::client_addr] replaces ${client_addr}. You don't need to use "use pool" in 9/10.x; just "pool POOL_239_2" works. Also, you can combine client IP addresses that you want to send to the same pool in an address datagroup to reduce the number of IP checks you do. If you do want to check a single IP address or network, you can use the IP::addr command.
Here are a few links:

} - hoolioThe classes need to be defined separately from the iRule. You can do this in the GUI under Local Traffic >> iRules >> Datagroup List tab >> Create >> Type: string. After you create the classes, you can then create the iRule which references them.

} - The_BhattmanHi Sumond,
Here is link to some instructions about creating data groups
https://support.f5.com/kb/en-us/solutions/public/6000/900/sol6911.html
These are not specific instructions for your case, but it shows you how to create Datagroup containing string information (which is URL info in your case)
I hope this helps
Bhattman - Sams_88783from where i can create theat CLASS object ?
