-----------------------------------

Thanks for the quick response, Kevin! Would you mind also merging this change to the 1.0.x-incubating branch?

> When the proxy handler receives a response that uses chunked transfer encoding, it retains the 'transfer-encoding' header in its own response, but doesn't actually send the response body in the chunked format.  This causes browsers & other clients to reject the response.
> This can be seen most easily when a gadget links to an external stylesheet on a server that uses chunked responses.
> For example, this gadget exhibits the problem: http://labs.atlassian.com/gadgets/lhardy/trunk/lhardy/gadget.xml
> The gadget itself loads normally, but its linked CSS file does not, so the contents are presented unstyled.
