 I've got two backends running apache2: front1.domain.com &
 front2.domain.com, set with the load balancing configuration from [http
 ://varnish-cache.org/wiki/LoadBalancing].

 The issue is, when I shutdown apache2 of the first backend varnish don't
 switch to the second and display "Error 503 Service Unavailable", is that
 a normal answer from varnish?

 Other question, does varnish load balancer keep php sessions, if yes how
 will I do?

 Varnishlog :
 {{{
 0 Backend_health - front1 Still healthy 4--X-RH 10 8 10 0.040008 0.039814
 HTTP/1.1 200 OK
 0 Backend_health - front2 Still healthy 4--X-RH 10 8 10 0.066948 0.066591
 HTTP/1.1 200 OK
 }}}

 Missing S flag "4--X-S-RH" to notify that TCP socket shutdown succeeded
 from [http://varnish-cache.org/wiki/BackendPolling]


 Part of default.vcl

 {{{
 backend front1 {
   .host = "front1.domain.com";
   .port = "80";
   .probe = { .url = "/";
              .interval = 10s;
              .timeout = 5s;
              .window = 10;
              .threshold = 8;
  }
 }

 backend front2 {
   .host = "front2.domain.com";
   .port = "80";
   .probe = { .url = "/";
              .interval = 10s;
              .timeout = 5s;
              .window = 10;
              .threshold = 8;
  }
 }

 director b1 random
 {
    { .backend = front1; .weight = 5; }
    { .backend = front2; .weight = 1; }
 }

 #director b1 round-robin {
 #    { .backend = front1; }
 #    { .backend = front2; }
 #}
 }}}


 Thanks for your help...
