Modifying the default block response page

We have ASM policies across several applications in our environment. One of the things we'd like to do is add some additional information to the blocking response page in order to give users more information (basically a help desk number) if they feel they've received a message in error.

 

We'd really like to be able to add this information to 1 place and have it affect all policies, not have to modify the response page of every ASM policy. Is there a way to do this? Maybe by modifying the default page?

    You can't modify the default policy. You could script the modification of the custom response in all policies using tmsh and just run the script once to loop through all policies and change them. Also if you have BIG-IQ managing ASM it can be done centrally from BIG-IQ

    Hi Effrum,

     

    An other option would be to choose the Redirect URL option for all ASM policies to redirect the user to an external website, e.g. ;

     

    With this option you have 1 central place where you manage the block page. Based on the Referer header you know from what webpage the user is coming and can decide to show additional or different content.
