Adding date and time to ASM response pages

Hi,

How can we add exact date and time when blocking occurs to ASM response pages? 

Thanks.

    Hi pinkzeppelin,

    this iRule should do:

     

    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 response "<html>
                     <head>
                        <title>Request Rejected</title>
                     </head>
                     <body>
                        The requested URL was rejected. Please consult with your administrator.<br><br>
                        The current time and date is: [clock format [clock seconds] -format {%H:%M:%S}], [clock format [clock seconds] -format {%d/%m/%Y}]<br><br>
                        Your support ID is: $asm_support_id<br><br><a href='javascript&colon;history.back();'>Go Back</a><br><br>


                     </body>
                  </html>"
   ASM::payload replace 0 [ASM::payload length] ""
   ASM::payload replace 0 0 $response
}

     

    Make sure to enable Trigger ASM iRule Events in your ASM security policy.

      Hi Daniel_Wolf 

      As a newcomer to iRule, I'm currently facing a similar issue. I'm seeking guidnace on customizing the blocking response page to send a negative response to clients, rather than the typical 200 OK. In the above iRule example, how do I implement it to show clients a 403 or 503 error code instead?

      Also, Does require to empty the default blocking response page setting if iRule is implemented?

      Thank you in advance.
