      Hi Mayur,

      Thank you for your answer, i do appreciate it.

      there are two conditions for the redirect:

      • all pool member is down?
        • is domain abc.com OR xyz.*?
        • then redirect to another vServer VS2 on the same ltm
  • I tried to manipulate it. Please check if it works for you.

     

    when HTTP_REQUEST {

         

    if { [HTTP::host] equals "abc.com" and { if { [active_members abc_POOL] == 0 } 

    }} {

    HTTP::redirect "https://redirect.com"

    }

    if { [HTTP::host] equals "xyz.com" and { if { [active_members xyz_POOL] == 0 } 

    }} {

    HTTP::redirect "https://redirect.com"

    }

    }

      I will diffidently try it and will let you know if it works.

      I have also made this one using the of google, what do you think about it?

       

      when HTTP_REQUEST {

      if {[active_members [LB::server pool]] == 0 } {

      if {(([string tolower [HTTP::host]] equals "abc.com") || 

      ([string tolower [HTTP::host]] equals "xyz.com") ||

      ([string tolower [HTTP::host]] contains "example"))

      HTTP::redirect "https://redirect.com"

      }

      }

      }
