when HTTP_REQUEST {
   get pool name
  if { [class match -- [string tolower [HTTP::host]] eq /ESI/wild.erp-dg] } {
    set hostvar [class search -value /ESI/wild.erp-dg eq [string tolower [HTTP::host]]]
  }
   check whether pool is down  
  if { [active_members $hostvar] < 1} {
    switch [string tolower [HTTP::uri]] {
      "/ufstyle.css" {
        HTTP::respond 200 content [ifile get ufstyle.css] "Content-Type" "text/css"
      }
      "/myuflheaderborder.jpg" {
        HTTP::respond 200 content [ifile get myuflheaderborder.jpg] "Content-Type" "image/jpeg"
      }
      "/myuflheader_bg.jpg" {
        HTTP::respond 200 content [ifile get myuflheader_bg.jpg] "Content-Type" "image/jpeg"
      }
      "/myuflheader.gif" {
        HTTP::respond 200 content [ifile get myuflheader.gif] "Content-Type" "image/jpeg"
      }
      "/myufllogo.gif" {
        HTTP::respond 200 content [ifile get myufllogo.gif] "Content-Type" "image/jpeg"
      }
      "/uflwordmark.gif" {
        HTTP::respond 200 content [ifile get uflwordmark.gif] "Content-Type" "image/jpeg"
      }
      default {
        HTTP::respond 200 content [ifile get $hostvar] "Content-Type" "text/html"
      }  
    }
   send to pool if pool is not down
  } else {
    pool $hostvar
  }
}
