Mr Mikw Snow

I want to use sockets to develop an online game, where I expect to create a socket server and number of client will connect to the server and get data from the server.

I do not want to use polling.

But as i search the web i find using socket server is not a solution, since Firewall, proxies block the port to communicate with the client and server sockets. And the other problem is i want to host the web on the internet on some asp.net web hosting provider. How am i supposed to start the server on the web host server.

If there are so many problems with the socket server, why is there a socket server available in .net.

What will be my feasible solution.

Please suggest what to do.

Thanks

Yes, a naming convention we use for class variables.

Thanks for the bug report.

Yes, there is a bug in this code: OnReceive should check for 0 _received. 0 indicates that socket is closed. Something like below:

// socket closed

if (_received == 0)

{

_connection.Close();

return;

}

It is a shame Microsoft cannot just package a policy server implementation in the Silverlight installation as a tool and has to use these blogs to show how to write one...

And what is the deal with '_' before field names? Some new naming convention?

I have forward your comments on to the SL team and we'll see if we can get a repro. I'll let you know what we find.

Thanks!

yes, it stays at 90%

what I figured out is that if i connect and disconnect for the first time, cpu stays on ~50% and if i do it one more time, cpu goes up to 90% and stays stuck.

F.e.:

1. CPU 0%

2. I connect to the server and disconnect (CPU 50%)

3. I connect to the server and disconnect (CPU 90%)

But if:

1. CPU 0%

2. I connect to the server, get the policy file and disconnect (CPU 0%)

...

n. I connect to the server, get the policy file and disconnect (CPU 0%)

So, if one client looses connection without getting the policyfile, my server CPU goes up to 50%, and if connection is lost one more time, my CPU is always on 90%.

Does it stay stuck at 90%?

Also, does it happen if you do not "quickly" connect and disconnect?

Thanks.

Hi,

I have some trouble with this implementation and I don't know how to debug it. Maybe you could help?

Problem: After starting this policy server, CPU usage goes up to 90%.

To reproduce the problem follow these steps:

1. start the server

2. connect and disconnect quickly a 2-3 times to this server without getting the policy file and the CPU will go up as I mentioned above.

As a TCP client for testing I use Hercules (www.hw-group.com/.../index_en.html) to connect to the policy server (TCP Client tab).
