[Varnish] #1131: Strange bug with if/lookup - else/pass in vcl_recv

[Guile SZK]

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.
