RE: [squid-users] Why ERR_ZERO_SIZE_OBJECT?

Hi Henrik,
 
I applied the workaround you suggested and did a quick test. It seems working. I would like to know what's the impact of this change.

Yes, I do see 1 mins delay between Squid sent the request and ERR_ZERO_SIZE.

Do you have any clue what is wrong here?
 
Thanks,

Didn't see any delay in the trace data, but maybe I overlooked
something.. The retry was within a few ms after the ERR_ZERO_SIZE.

Hmm.. if you see a long delay between Squid sent the request and
ERR_ZERO_SIZE then something is wrong at the web server, eating the
request without responding to it.

You can most likely work around the issue by
"server_persistent_connections off". Will cost a little in added
latency, but if the serer is close to the proxy then it's marginal.
