Hi,

<html>
<head>
<title>Request Rejected</title>
</head>

The requested URL was rejected. Please consult with your administrator.<br><br>
Your support ID is: $supportid <br><br><a href='javascript:history.back();'>[Go Back]</a>

set asmstatus "blocked"
set supportid [ASM::support_id]
}
when HTTP_RESPONSE_RELEASE {
# log local0. "ASM Status = $asmstatus"
if { $asmstatus equals "blocked" } {
# log local0. "Support ID = $supportid"
HTTP::respond 500 content [subst -nocommands -nobackslashes [ifile get asm_custom_response]]
}
}
ebrcThank you eaa!
I will try and give feedback then.
There is no way to just keep the ASM blocking page from ASM policy (that we already replaced by the customer's one) and just replace the error code?
I think your way will work, but we will have to maintain the same blocking page in 2 different places (ASM + ifile)
