Hi Ketzuken,

Is the value of "Location" header you're trying to use in your conditional switch statement? If so, try to replace 

switch -glob [HTTP::header "Location"]
with 
switch -glob [HTTP::header value "Location"]
.

Additionally, you may find it useful to include a log statement for the duration of troubleshooting and testing. 

log local0. "[HTTP::header value "Location"]"
. If this log statement returns an empty value to 
/var/log/ltm
, you'll know the "Location" header was not included in the HTTP response.
