Redirection iRule on ASM Blocking
Hello,
I need an iRule to redirect to home page when the ASM blocks a request.
I know that this can be achieved by selecting a redirect url for the response page instead of using the default response page but I need something more general for I have multiple applications and I want to manage that in an iRule.
I have tried the following iRule but it's not working:
when ASM_REQUEST_BLOCKING {
HTTP::redirect https://[HTTP::host]/
}
Thanks,
Bayan El Ameen
- nitassEmployeethis is another way round.
- Jim_Sellers_106NimbostratusWhat version of ASM are you running ? I currently do this all the time with the URL redirect option in the blocking response tab under the policy option.
- Bayan_El_Ameen1NimbostratusI'm running 10.2
- John_Alam_45640Historic F5 AccountHTTP Redirect is a "server-side" command. At the REQUEST_BLOCKING stage, the request has not reached the server and therefore there is no server response and no "server-side" events.
- Bayan_El_Ameen1NimbostratusThanks for the clarification John. I think the HTTP_CLASS_SELECTED would solve this issue
- nitassEmployeethis is mine.
