replace http response code of fallback host reply

You cannot do this from an HTTP profile but would be able to do so using a Local Traffic Policy or an iRule.

Hi Nicolas,

You can replace the Fallback Host feature using LB_FAILED event within an irule :

when LB_FAILED {
    HTTP::respond 302 observer Location "http://www.example.com/maintenance.page" Connection Close
}

That's an example, you can customize the HTTP respond to fit your needs.

Regards

Yann
