First a little on findclass and matchclass. matchclass will search a data group list for an exact string match while findclass will search for a string in the class that starts with the search string. Either should work for your case but I just wanted to make clear the subtle difference.

So, the answer to your question really depends on what you have defined in your data group list as well as in the cookie. If you have the cookie being set in the format of "xx ip_addr:port", then since you are including the port in the cookie, you will have to explicitly state all values in the data group list.

Another option would be to include only the IP Addresses in the data group list and use the getfield command to break apart the cookie value into address and port before searching.

 
 // assuming $server is of the form "xx ip4_addr:port" 
 set server_addr [getfield $server ":" 1];

You might want to throw in some "[info exists var]" in there to make sure you don't get runtime errors on the assignment commands for undefined variables - check in the /var/log/ltm logfile for any signs of this. You'll get something like this if you try to reference an undefined variable

can't read "varaible_name": no such variable

Once that is done, you then can do a matchclass (or findclass) on the extracted addr

set entry [findclass $server_addr $::staging_nodes]

Hope this helps...
