Varnish sends additional Date header with the date when the object was
first fetched (on first request the dates are identical).


{{{
wget -S http://10.0.0.1/251324940.jpg

HTTP/1.1 200 OK
Date: Thu, 08 Mar 2012 17:47:45 GMT
Content-Type: image/jpeg
Last-Modified: Thu, 08 Mar 2012 17:23:43 GMT
Expires: Thu, 31 Dec 2037 23:55:55 GMT

}}}

and a second request (after ~10 sec)

{{{
HTTP/1.1 200 OK
Date: Thu, 08 Mar 2012 17:47:45 GMT
Content-Type: image/jpeg
Last-Modified: Thu, 08 Mar 2012 17:23:43 GMT
Expires: Thu, 31 Dec 2037 23:55:55 GMT
Cache-Control: max-age=315360000
Content-Length: 126142

Age: 9
Connection: keep-alive
X-Cache: HIT
}}}

On both requests there are 2 Date headers.
Can be seen also from varnishlog:


{{{
2738 TxResponse c OK
2738 TxHeader c Date: Thu, 08 Mar 2012 17:47:45 GMT
2738 TxHeader c Content-Type: image/jpeg
2738 TxHeader c Last-Modified: Thu, 08 Mar 2012 14:11:23 GMT
2738 TxHeader c Expires: Thu, 31 Dec 2037 23:55:55 GMT
2738 TxHeader c Cache-Control: max-age=315360000
2738 TxHeader c Content-Length: 126142
2738 TxHeader c Date: Thu, 08 Mar 2012 17:47:45 GMT
2738 TxHeader c Age: 0
2738 TxHeader c Connection: keep-alive
}}}

Doesn't happen with 2.1.5.
