Any help is > appreciated. Thank you in advance. You appear to be confused by proper HTTP behavior. The web server responds in whatever way it needs to for the requests that comes in. Squid is not capable of HTTP/1.1 and so sends HTTP/1.0 requests as it is required to do. The only possible thing like a bug I can see here is that squid _might_ be transforming a TE: encoding request into a Content-Encoding: and the client unable to handle such encodings despite needing to. We need the headers input into squid from the client vs the headers sent to Server to see.
