NimbostratusUsing wildcards with classes
I'm in desperate need of help with an iRule for a customer. They are converting a working 9.x rule to 10.x. In the process we changed it from an array to a class. The class calls an external file with 8998 lines (I know it's rather large). What they are doing is redirecting on the HTTP Response. They read the name from the class and then redirect (301) with the value.
The redirection portion works perfectly. The problem is that the name portion has a lot of wildcard URIs and I can't figure out how to deal with them.
I'm posting a portion of a test data set, the current iRule, and the class commands from the config. I would really appreciate any help I can get.

Once again, I would appreciate any help at all.
