Normal correct behaviour. I see no problem there.

  * Chunking is not an HTTP/1.0 feature.
  * content which gets chunked is "unknown length"
  * HTTP/1.0 software is required to close a connection to signal
end-of-object. Which chunking was created in 1.1 to avoid.

If you want end-to-end HTTP/1.1 with chunking you need Squid-3.2 beta
software. 2.7 series can advetise HTTP/1.1 but does not relay the chunking.
