Return ASM Violation in Response
Hey folks, Is it possible to return the ASM violation in the response body? If so, what does that logic look like?
I don't know how to do it in simple way, but you can try to use ASM iRule for this purpose.
Something like this:
when ASM_REQUEST_BLOCKING {
set x [ASM::violation_data]
#c_ stands for "custom"
set c_brp "<html>
<head>
<title>This is a custom BRP!</title>
</head>
<body>
<h1>The request was blocked and next violations were detected: [lindex $x 0].</h1>
</body>
</html>"
set c_brplen [string length $c_brp]
HTTP::header replace "Content-length" $c_brplen
#ASM already formed a BRP, so we delete it first and place ours instead
#d_ stands for "default"
set d_brplen [ASM::payload length]
ASM::payload replace 0 $d_brplen $c_brp
}
Thanks, Ivan
