Node.js - controlling the size of a POST request

Question

I have a program in Node.JS, using Express. When I do a POST request to this program, what is the maximum accepted size for the data in the request? Is there any way to set this size?

If you are using Express, you can use the limit middleware: http://senchalabs.github.com/connect/middleware-limit.html

If you are interested in it's implementation, it does something like this:

// limit
req.on('data', function(chunk){
  received += chunk.length;
  if (received > bytes) deny();
});
