[squid-users] Illegal character in hostname '!host!'

I'm seeing this error on occasion and trying to figure out how to
capture what is causing it.

2010/05/04 11:06:03| urlParse: Illegal character in hostname '!host!'

!host!.

I've thought maybe it was actually in a URI but I've added access
logging with urlpath_regex -i \!host and nothing is matching.

Is the !host! possibly internal to squid?

How do I go about capturing and figuring this out?

Thanks
