Hi all,
In servlet 3.1 we have to support assync io and upgrade to raw
buffering, would that work with traffic server.

I'm not familiar with servlet, doing some Bing'ing, it seems to be a
Java spec, JSR 340? Is that it?
Yes it is JSR 340.
ATS obviously supports asynchronous I/O, it's a fundamental part of the
design (everything is asynchronous). What exactly do you mean with raw
buffering? You want to upgrade the HTTP connection to some other protocol?
Yes it is a kind of upgrade to no protocol the data are send and
received in a raw mode until the connection is closed. In Tomcat we get
that by removing all filters. We use that for websocket for example:
GET /all//upgrade00 HTTP/1.1
host: localhost
HTTP/1.1 101 Switching Protocols
Server: Apache-Coyote/1.1
Set-Cookie: JSESSIONID=iVE2KWOuBlsUGx87Do3mRPbx; Path=/all
Upgrade: WebSocket
Sec-WebSocket-Protocol: sample
Connection: Upgrade

And then we handle the websocket protocol in the servlet logic, which
requires traffic server to proxy raw data.
