LinuxQuestions.org - squid error 22 during POST

Hi all,

I have squid running as a transparent proxy on my ADSL gateway/server box. For the most part it works fine and is indeed transparent to the LAN clients.

However, I am encounting a recurring error when managing a remote website running Joomla. When I submit changes to pages I regularly see an error message from Squid:

Code:

The system returned: (22) Invalid argument



The remote host or network may be down. Please try the request again.

If I click the back button in the browser, it usually works the second time around, but it is annoying.

The site is physically nearby and latency is low.

Anyone have any idea what is going on here? Neither access.log or cache.log are telling me anything useful, but I can see it happens with the HTML POST command.

Thanks
