 Hi !

 It's done, we found how fix it.

 Our infrastructure :
 VH : Varnish
 ACE : Cisco ACE
 WEBS : Thousand web servers (Apache)
 WEBX : web server

 Step by step :
 1° VH <-> ACE <-> WEBS
 2° VH --> ACE (Cookie? Yes:Set-Cookie=$cookie,
 No:Set-Cookie=newcookie()) --> WEBX
 3° VH --- ACE Transparent mode --> WEBX
 4° VH <-- ACE Transparent mode --- WEBX

 Some responses were back from backend to VH without "Set-Cookie" field.
 Web servers had keep-alive enable, so when VH reuse connections, step2
 was ignored.

 We had disable keep-alive connections on web servers, and all is fine :)

 Guile.
