Disable HTTP/1.1 using F5 load balancer

 
  From http://devcentral.f5.com/wiki/default.aspx/iRules/CreditCardScrubber.html 
 when HTTP_REQUEST { 
  
     Don't allow response data to be chunked 
    if { [HTTP::version] eq "1.1" } { 
  
        Force downgrade to HTTP 1.0, but still allow keep-alive connections. 
        Since HTTP 1.1 is keep-alive by default, and 1.0 isn't, 
        we need make sure the headers reflect the keep-alive status. 
  
        Check if this is a keep alive connection 
       if { [HTTP::header is_keepalive] } { 
  
           Replace the connection header value with "Keep-Alive" 
          HTTP::header replace "Connection" "Keep-Alive" 
       } 
  
        Set server side request version to 1.0 
       HTTP::version "1.0" 
    } 
 }
