Irule to External Data Group not pulling up second data field

The [HTTP::uri] command will always return at least "/", even if no URL path is specified, so most of your samples won't ever match. You should see that in your log statement:

if {$static::redir_debug}{log local0. "Match String: $match_string"}

With a call to "admissions.ou.edu", which should return:

admissions.ou.edu/ 

If in your log statement you see, for example:

Goto: pool,ouwww_bostitch,

But you see nothing from:

[getfield $goto "," 2]

then there's another issue that might be better solved with a list function. But I'm more inclined to think its a data group matching issue still.
