iRule to ping host

This is what I'm using, although the original code had the HTTP::uri as "/whichserver". I seemed to get the same result with the whichserver variable or the site uri. So, I should see the "Real ServerIP...." in the webpage? I'd rather have something in a header to the client.

 

 

when LB_SELECTED {

 

set whichserver [LB::server addr]

 

}

 

when HTTP_REQUEST {

 

if { [string tolower [HTTP::uri]] equals "website.domain.net" } {

 

HTTP::respond 200 content "Real server IP is: [LB::server addr]" noserver Content-Type "text/html" Connection "Close"

return

 

}

 

}
