Hello, please find below the irule reposted. The badlink is trapped here :

when HTTP_REQUEST {
 if {[HTTP::host] eq "www.service.com" and [HTTP::uri] starts_with "/_badlink/" } {
    switch -glob [string tolower [HTTP::uri]] {
        "*.pdf" {
            set message "illegal file download !!!"
            HTTP::respond 200 content [subst -nocommands -nobackslashes [ifile get message.html]] noserver "Content-Type" "text/html"
        }
    }
 }
}

You can create an ifile by importing your html content in System > File Management > Import ifile

Then you create an ifile object that refer to the ifile content previously imported in Local Traffic > iRules > iFile List. In the irule you refer to the ifile object created in iRules > iFile List tab

For the html content itself, it's up to you to create an html message with your own look&feel. The bonus is that you just have to set $message in the html file where you want the irule to replace this variable by the value.
