HTTP pipelining broken after upgrade to UTM 9.3

ondrej.holas
In 9.2, the HTTP pipelining works well on HTTP proxy:

$ telnet 192.168.1.22 8080
Trying 192.168.1.22...
Connected to 192.168.1.22.
Escape character is '^]'.
GET 192.168.1.2/.../1.1
Host: 192.168.1.2

GET 192.168.1.2/.../1.1
Host: 192.168.1.2

HTTP/1.1 200 OK

test2
^]
telnet> q
Connection closed.


In 9.3 (tested on 9.304-9 and 9.305-4), HTTP proxy processes only the first request and times out after one minute:

$ telnet 192.168.1.22 8080
Trying 192.168.1.22...
Connected to 192.168.1.22.
Escape character is '^]'.
GET 192.168.1.2/.../1.1
Host: 192.168.1.2

GET 192.168.1.2/.../1.1
Host: 192.168.1.2

HTTP/1.1 200 OK

Content-Length: 6
X-Frame-Options: deny
Keep-Alive: timeout=5, max=100
Content-Type: text/plain
Proxy-Connection: keep-alive

test1
Connection closed by foreign host.


The second request is neither processed nor logged in /var/log/http.log.

Real world scenario affected by this bug is Debian apt configured to pipeline requests (by default in squeeze).

Maybe something to do with changes in ID31116.

Brgds,

Ondrej

    We've built a very simple .Net program that demonstrates Ondrej's problem on SG210 / 9.352. Downloading map tile files with .Net (WebClient), asynchronous download. With pipelining on, first 6 tiles come quickly, then a pause for exactly 60 seconds before the rest arrive. With pipelining disabled, map tiles flow freely. Is support looking at this issue?
