Ralf, Yes. The socket proxy server will ship as an IFBIN example combined
with full source for the server as well. There will be an example using Flex
2 that utilizes the example.
At Spark Europe I showed an HTTP Client I wrote using flash.net.Socket that
allow you raw access to HTTP headers and more. Using this library in
production is problematic because connections to other HTTP servers from
Flash is not permitted for good reason. Using the Socket Proxy, you can make
this work seamlessly along with accessing any TCP/IP based socket protocol.
The main purpose for the proxy's development is actually to scale out the
Comet AMF Socket Server using clustering. The proxy can be easily modified
to provide a clustering solution for any type of socket server in that the
proxy server maintains client connections while the data is multi-plexed to
a central server. Works sort of like so:
X == Frontline Connection Servers
B == BackEnd Logic Servers
X X X X X X X X ---> N
| | | | | | | |
======================
| |
B -- B
The backend logic server is where the logic is actually executed. You can
create several backend servers for failover where all live data is mirrored.
Should a backend server overload, crash, or go postal, processing will
failover to another backend server.
We used this model with an XMPP server rollout 4 years ago and tested
support for over 30,000 concurrent connections. XMPP is a much heavier
server and the Comet model is much lighter and faster. Plus you can write
your own server logic and use this model to scale deployment for lots of
concurrent users.
Personally, I think we will see some very large MMPG's for Flash Player 8.5
and we designed this as a solution to scale the server side.
This server will also be in IFBIN but we need some time for the dust to
settle and to resolve a protocol licensing AMF issue. As AMF is a Macromedia
protocol, we are working to make sure our server does not violate any
property rights before the code ships. We are working with Macromedia
directly to get this resolved.
More to come!
Ted ;)
