Nonblocking sockets with Select
I do not understand what the difference is between calling recv() on a non-blocking socket vs a blocking socket after waiting to call recv() after select returns that it is ready for reading. It would seem to me like a blocking socket will never block in this situation anyway. Also, I have heard that one model for using non blocking sock...

Users connect to our webserver via https, and stay on a secured connection throughout their use of our service. A typical user session will establish a small handful of connections to the server (one or two). There are a very small number of exceptions we are trying to track down. Particular users will intermittently have handfuls of ...

Possible methods to send the output of a PHP-invoked .exe program (that runs as a separate process, not in PHP) back to the iPhone client
My iPhone client app uploads a data to the server, which runs on PHP. There is a code to invoke a .exe program on the server side on PHP. The .exe program will take the uploaded data and run on a process on its own. That means the PHP execution will end without waiting for the .exe program to finish. After the .exe program finished proce...

Caveats of select/poll vs. epoll reactors in Twisted
Everything I've read and experienced ( Tornado based apps ) leads me to believe that ePoll is a natural replacement for Select and Poll based networking, especially with Twisted. Which makes me paranoid, its pretty rare for a better technique or methodology not to come with a price. Reading a couple dozen comparisons between epoll and ...
TCP disconnection if no data
Hi! I've checked out TCP protocol Wiki, but haven't found, if socket connection will time out if no data is transferred during the long period. I mean.. there will be no physical problems, but two computers will just have no data to send each other for some time. How connection will still exist? Will there be some low-level data transfer...
