[squid-users] Help with extension_methods

I found some errors in my cache.log file this afternoon, I have tracked it down to a development machine and know that they occurred while the developer working on the machine was doing a build out of Plone, which did in the end succeed so I am not sure this is a huge concern but would rather not have the errors in the future if it can be fixed.

There were several entries like this in the access.log:
1264442419.041 0 10.20.147.34 NONE/400 1806 NONE error:unsupported-request-method - NONE/- text/html

That corresponded to entries like this in the cache.log:
2010/01/25 12:03:35| clientParseRequestMethod: Unsupported method attempted by 10.20.147.34: This is not a bug. see squid.conf extension_methods
2010/01/25 12:03:35| clientParseRequestMethod: Unsupported method in request '_z___'

I checked on the extension_methods, but am a little confused as to what to enter for the method? To possibly solve this issue, would I just use the following configuration line?
extension_methods _z___

If anyone could point me in the right direction to find some resources on this issue it would be greatly appreciated. I tried searching but didn't find any information on _z___ on the web. I am currently running squid3.0.STABLE21.
