Hi,
We use Squid 3.1.20.
We are often exposed to a problem which return a "Zero Sized Error".
Can i fix it with some options on the squid configuration file ?
I tried all of things mentioned after :
- Delete or rename your cookie file and configure your browser to
prompt you before accepting any new cookies.
- Disable HTTP persistent connections with the
server_persistent_connections and client_persistent_connections
directives.
- Disable any advanced TCP features on the Squid system. Disable ECN
on Linux with echo 0 > /proc/sys/net/ipv4/tcp_ecn/.
I will try to find the origin of the problem with a tcpdump on my
proxy my i don't known how could i exploit it.
This is the result of the TCP stream between my proxy and the website :
GET / HTTP/1.1
Host: www.mopub.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:17.0) Gecko/20100101 Firefox/17.0

And between the proxy and the client :
