[Seaside] HTTP server streaming (was My progress with Seaside...)

[Janko Mivšek]

Dear all,

Streaming on a HTTP 1.1 servers is a bit more difficult than on old 1.0 
ones because a TCP connection stays open during many HTTP requests. To 
know when each request ends, it must therefore report an exact length 
and this is the reason why we need the entire response in advance before 
sending to a client.

But there is also a solution around: see HTTP 1.1 standard 
http://www.ietf.org/rfc/rfc2616.txt, section 3.6 Transfer Codings. It 
seems that "chunked" transfer coding enables streaming!

Best regards
Janko
