Does anyone have an idea why this would not work with 209.162.186.60 pulled from a string? I am executing this statement:

 

 

 

set a "209.162.186.60"

 

log local0. "catch $a => [catch {IP::addr $a mask 255.255.255.255} ]"

 

log local0. "catch $hostname => [catch {IP::addr $hostname mask 255.255.255.255} ]"

 

log local0. "hostname = \[$hostname>\]"

 

 

$hostname was pulled from a header using set hostname [HTTP::header "X-HOSTNAME"].

 

 

This is the result of the log:

 

 

Rule OutboundSSLRouter HTTP_REQUEST: catch 209.162.186.60 = 1

 

Rule OutboundSSLRouter HTTP_REQUEST: catch 209.162.186.60 = 0

 

 

 

Rule OutboundSSLRouter HTTP_REQUEST: catch 209.162.186.60 = 1

 

 

Is there anything special about a variable pulled from HTTP::header?
