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"

}

}

}
