Hello, I am designing a application where many clients connect to a central server. This server keeps these connections, sending keep-alives every half-hour. The server has a embedded HTTP server, which provides a interface to the client connections (ex. http://server/isClientConnected?id=id). I was wondering what is the best way to go a...
I'm new to Flash. I'm planning to create a game client in Flash (running in browser) that needs to talk to a server written in Java. Connection between client and server needs to be persistent. I'm aware of XMLSocket - is that the only way to go? Any recommendations? Thanks! ...
I use the following code to layout network drives on a system. I want to add a third column for persistence but in vb.net I do not know how to check if a drive has a persistent map or not. Any suggestions? For Each drive_info As DriveInfo In DriveInfo.GetDrives() If drive_info.DriveType().ToString = "Network" Then Wi...
How can I write Http server in TornadoWeb that will support persistent Connections. I mean will be able to receive many requests and answer to them without closing connection. How does it actually work in async? I just want to know how to write handler to handle persistent connection. How actually would it work? I have handler like t...
I have recently been exploring the Tornado web framework to serve a lot of consistent connections by lots of different clients. I have a request handler that basically takes an RSA encrypted string and decrypts it. The decrypted text is an XML string that gets parsed by a SAX document handler that I have written. Everything works perf...
I am doing HTTP POSTs very frequently (>= 1/sec) to an API endpoint and I want to make sure I'm doing it efficiently. My goal is to succeed or fail as soon as possible, especially since I have separate code to retry failed POSTs. There is a nice page of HttpClient performance tips, but I'm not sure if exhaustively implementing them all w...

There are parts of my app where a persistent connection is required, in particular the parts where every hour maybe 30,000 select requests are made by many different users, this is causing my mysql server to max out on the 100 connection limit, and i really don't want to increase it since 100 connections already seems like alot. So for t...
We have an app with a long polling scheme over HTTP (although this question could apply to any TCP-based protocol). Our timeout is fairly high, 30 minutes or so. What we see sometimes is mobile devices hop from IP to IP fairly often, every minute or so, and this causes dozens of long-lived sockets to pile up on the server. Can't help bu...
