title: Possible to enable Keep-alive with a load balancer?
body: <p>I'm trying to optimize my web application using Google's Page Speed API which has highlighted the absence of "Keep-alive" in my HTTP response headers as a major page speed weakness.</p>
  
  <p>In talking with my back-end devs and sys admins, they've told me that using Keep-alive on the site is impossible because we use a load balancer.</p>
  
  <p>I'm wondering, is this accurate? Are there load balancers that support Keep-alive?</p>
  
  <p>It seems strange to me that the Page Speed API would complain about Keep-alive if it were impossible to use with load balancers because I would imagine a fair amount of applications and large sites use load balancers.</p>
  
  <p>Thanks!</p>
