They are mostly using GET but there were a couple of HEAD requests. The requests are coming from cloud accounts on Google and Amazon. They are using several variations of the URL most get 404 errors, which is responded with by a custom
404 page, this is the only one that is getting a 400 error.

Subject: Re: [users@httpd] Questionable URL being sent to our server
What is the HTTP method you see in the logs?
Either way, they may trying to use your server as an open proxy, and failing to do so.
We are getting a poorly formed URL being requested from our servers. Apache is returning a 400 error but I am wondering
if someone is try to exploit an issue with some version of some web server out there. Maybe a Dos attack or worse. Anyone have a clue what is being attempted?
