Another question on using mina as a proxy server.
Hi, I'm basically attempting to use mina to act as a
proxy server something like discussed in the previous
example:
http://www.nabble.com/-MINA-Using-MINA-to-write-a-proxy-server-like-application-t656623.html
However, the case I have is not 1:1 on the client and
server session basis.
The situation I have involves a client which spawns
multiple processes, each opening its own connection to
my proposed mina server. The mina server itself has a
persistent fixed amount of connections to the actual
server to distribute the client requests with. The
client connections are short lived are only open to
process a single request while the mina->server should
always be open.
Client 1<---------|
| Persistent Conn 1
Client 2<--------|| |-------------->
Mina Server Actual Server
Client 3<--------|| |-------------->
| Persistent Conn 2
Client 4<---------|
The amount of client connections is variable but the
connections from mina to the actual server is always
fixed. My question is, what is the best way to demux
the responses from the actual server to the
appropriate client? One of the fixed mina->server
sessions may have several client->mina sessions
attached to it at one time. Is there something Mina
provides to do this or do I need to come up with some
home grown based version?
Thanks, S.D.

Even I need something like this. If you dont mind, do keep us posted
about the approach you plan to take. The challenge is to keep the
mina proxy agnostic of the application protocol. Trustin, remember I
was talking about this same thing a few days ago? This would be
really cool for HA server apps.

Vinod.

Your response is what I was sort of expecting but
wasn't sure if there might've been something behind
the scenes mina provided that I could use.
Thanks though for the quick response.

It takes some time for you to get a response; because it's an open source
software. It can even take a week. :)

There's no special way to implement it. To do so, there has to be an
identifier for each message so you can determins which message belongs to
which client. Plus, the proxy should be able to interpret the message so it
can extract the ID field. That's all.

Nobody has any suggestions on using some form of mina
provided approach for this?
Thanks, S.D.
