Evaluating data pulled from a data group

I stepped back and went at this a little different way. I created 3 datagroups and constructed my if statement to evaluate the contents of the datagroups. Now if the following paths are hit, it is properly redirected to the new URL.

http://domain.com/abc

http://domain.com/xyz/123

The NOT portion of the statement is not working yet. Any ideas?

http://domain.com/abc?x=y

datagroup_http_path_equals

datagroup_http_path_contains

datagroup_http_query_not_contains

if { ( [class match [string tolower [HTTP::path]] equals ${datagroup_http_path_equals}] || [class match [string tolower [HTTP::path]] contains ${datagroup_http_path_contains}] ) and not ( [class match [string tolower [HTTP::query]] contains ${datagroup_http_query_not_contains}] ) } {Redirect to new url}
