Re: The HTTP header to be used for a gzip message

Hi,

We do support Transfer-Encoding:chunked.  When a message is gziped it has to
be a chunked message. Which means if  we use the Transfer-Encoding header
to  indicate gzip, the same header has got to indicate chunked too.  I tried
this combination  with tomcat at the server. The server understands the
message only if the headers are placed as following

Transfer-Encoding: chunked
Transfer-Encoding: gzip

If we reverse the order it returns a 501. The same occurs if we use
"Transfer-Encoding: chunked,gzip " or "Transfer-Encoding: gzip,chunked ".

Taking this into account I'm still not sure which header we should be
using...

What do u think Philippe

Thanks,
Keith.
