Zero Sized Reply error massage

[Lynux]

Apache suddely started giving me a strange error message:
--------------------------------------------------
ERROR
The requested URL could not be retrieved

----------------------------------------------------

While trying to retrieve the URL: myURL

The following error was encountered:
Zero Sized Reply
Squid did not receive any data for this request.

Your cache administrator is webmaster.
----------------------------------------------------

Anyone have any idea what is causing this?? =================================

Hi,

The message relates to a problem experience by the squid cache proxy and not apache as such. That messages seems to just indicate some kind of failure by squid to retrieve a given page (or item) after repeated attempts. If you go to -->

http://www.squid-cache.org/

and type 'zero sized reply' in the search box you will see quite a few similar problems that others have had but, unfortunately, no obvious solution.

What happens if you access the same site direct (not via squid proxy) ?

Regards

Thanks a ton for the lead...
How do access the site note using squid?.. I am not real familier with squid.


thanks again! =================================

Hi,

Its a little difficult to answer that directly as there are a few possibilities. If you have access to the box on which squid is running you can just use a browser from there, making sure that is NOT configured to use a proxy server.

If its linux, you could also use (maybe temporarily) IP masquerading instead of squid to share the internet connection from that box. IP masquerading is a specialised form of source nat that is very simple to set up with either 'ipchains' or 'iptables'. For example with iptables :

echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/modprobe iptable_nat
/sbin/iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth1 -j MASQUERADE

That would masquerade all traffic out of interface -o (e.g. eth1) from a source of the lan subnet 192.168.1.0 / 255.255.255.0 . All the clients need is a default route of the masquerade box plus they need to be configured with the appropriate dns server addresses because (unlike squid) masquerading doesn't transparently do any name resolution - it just forwards packets.

You'd also configure the client browser to NOT use proxies.

Hope this helps
