Re: [squid-users] chunked encoding is not working after squid-2.6Stable9

I didn't think that a transfer-encoded response was valid to a HTTP/1.1
request.

The latest Squid-2.6 will decode the chunked response and return a valid HTTP/1.0
body (minus chunking.)

Its possible the server and client application are broken?
