Thread: simple proxy

Hi all, I have to program a proxy who will accept connections from multiple clients. The proxy must identify the client with logins and passwords stocked in a file. The clients tranfer blocks of 100 characters to the proxy. The proxy push those blocks in a circular buffer and then send the blocks to the server at a slower rate. The proxy has to tell the clients to wait or continue when the circular buffer is full or empty. Also, the server has to check the crc of each block.

Anyone knows about some examples ???

Thanks

Now THAT'S what I call "in over your head"....

Sockets, ACLs, buffering, rate difference, dogpile arbitration and content validation...

Good luck with that.

That would be what? 3rd year? And by then he should be off to the races with it...

This is an assignment !

I'm ok with socket and circular buffer. But I know I will have some problems with threads. I will probably find a way to slow the rate and calculate crc with some research. What would really help me is an example of multithreaded server.

Google is your friend.
