Customize the default Blocking page

Has anyone been able to customize the default ASM Blocking page to contain any other variables other than the support ID? It appears that the support_id is part of structure, (see below), that contains other data elements that I would like to display on the blocking page, specifically the web_application value. I've tried to add these variables to the blocking page but when I trip a signature it displays the support_id correctly, but the rest is displayed as just plain text, nothing is resolved to a value.

 

Any help would be appreciated.

 

{ log local0. "support_id=[lindex $x $i]" }

 

{ log local0. "web_application=[lindex $x $i]" }

 

{ log local0. "severity=[lindex $x $i]" }

 

{ log local0. "source_ip=[lindex $x $i]" }

 

{ log local0. "attack_type=[lindex $x $i]" }

 

{ log local0. "request_status=[lindex $x $i]" }
