HTTP::redirect for "vanity" URLs?

Question

I have what I think is a simple http::redirect request, but
cannot seem to craft an iRule that works... Here's the idea -  I'd like any
request to a particular wideip (say, HTTP_REQUEST to gtmfoo.wideip.company.com)
to be redirected to a different URL.  The goal is to create "vanity"
dns entries that the GTM can return a specific URL for.  So, I can create a
CNAME for "gtmfoo" that points to FQDN gtmfoo.wideip.company.com. 
Upon getting an http request to this wideip, a redirect is sent back with a particular URL, say
http://support.f5.com/kb/en-us...wbr&gt;. 
&nbsp;
The net effect - user types "gtmfoo" into their
browser and and gets sent to
http://support.f5.com/kb/en-us...wbr&gt;.&nbsp;
This seems like a relatively straightforward thing, but I
cannot seem to put together anything that works.  Below are a few attempts I've
tried based on things I've cobbled together in the forums - where am I going
wrong? Thanks in advance for any help you can spare - still getting the hang of
my iRules...&nbsp;

ATTEMPT 1:
&nbsp;
when HTTP_REQUEST {&nbsp;
   HTTP::redirect
"http://support.f5.com/kb/en-us...wbr&gt;"&nbsp;
   log local0. "[IP::client_addr]:[TCP::client_port]:
Redirecting request"&nbsp;
}&nbsp;
 &nbsp;

ATTEMPT 2:
&nbsp;
when HTTP_REQUEST {&nbsp;
  if { [HTTP::host] contains "gtmfoo"} {&nbsp;
    HTTP::redirect
"http://support.f5.com/kb/en-us...wbr&gt;"&nbsp;
                log local0.
"[IP::client_addr]:[TCP::client_port]: Redirecting request"&nbsp;
 }&nbsp;
}&nbsp;
 &nbsp;

ATTEMPT 3:
&nbsp;
when HTTP_REQUEST { &nbsp;
  if { [http::path] contains "gtmfoo" } {&nbsp;
    http::redirect location
"http://support.f5.com/kb/en-us...wbr&gt;"&nbsp;
                log local0.
"[IP::client_addr]:[TCP::client_port]: Redirecting request"&nbsp;
 } &nbsp;

There is nothing wrong with your rules, the problem must be with where you are implementing it. These rules will need to be assigned to an LTM virtual server. If you are assigning the rules to GTM pools the HTTP_REQUEST event will not be triggered. Could that be your problem?

LOL - yes, I believe it is.  Stepping back and thinking about it, the GTM is only DNS - it's just going to kick back the virtual server IP.  Let me get this implemented on an LTM and point the GTM to it, and I can report back.  Thanks for the help - i figured it was something dumb! :)
