You need to follow the next steps:

- Change to the correct "Current edited security policy"
Create an iRule with content similar to the following (add/delete fields as needed):
when HTTP_REQUEST {
# Other HTTP values can be added here
set requri "http://[HTTP::host][HTTP::uri]"}
when ASM_REQUEST_DONE {
set asm_support_id [ASM::support_id]
}
when ASM_REQUEST_BLOCKING {
HTTP::header remove Content-Length
HTTP::header insert header_1 value_1
set client_ip [IP::client_addr]
set response "<html>
<head>
<title>Request Rejected</title>
</head>
<body>

Rafi1Hi,
Thank you for your response,
