Hi Nick,

the command 

[string match -nocase $test_path_regex $path]
isn't using RegEx. Its rather using a 
-glob
matching syntax (
*
, 
?
or 
[A-Za-z0-9]
wildcards). So just use...

set test_path_regex "/investing/general/2016/*.aspx"
set test_path_regex "/investing/general/2016/*.aspx*"

For more information: http://www.tcl.tk/man/tcl8.4/TclCmd/string.htmM34

General Note: You should avoid using RegEx in iRules as much as possible. Its terible slow and most of the stuff can be already done using -glob matchings.

Cheers, Kai
