Out of curiosity, what is the motivation for writing your own web server? There are a lot of them out there already. It's non-trivial to write one that scales well, as you have to use asynchronous methods for it to scale (even a little) and they're not nearly as easy to grok. There's a sample of an asynch server on MSDN:
http://msdn2.microsoft.com/en-us/library/fx6588te.aspx Unfortunately for you, it doesn't have the problem you've got, because it uses a home-grown very much non-robust "protocol" to figure out when the data being sent has ended. Back to your question -- there's no Accept method; I assume that you meant AcceptSocket. You don't use that to "get all the data" -- as I think you know, you use the Socket that it returns to get the data, and there's no direct way to get it all. (In theory, it could return a huge amount of data; if you're expecting a big transmission, you'll need to write it to disk as it comes in or you'll be in trouble.) If you use BeginReceive, I don't believe that you'll have the problem -- once your callback has happened, either there's data or the other end has finished (by closing the socket, or by sending all that it should have sent according to the ContentLength header). When you call EndReceive (in your callback method), it should return immediately (else the callback wouldn't have happened) and if it returns 0, you know you're done. Look at this sample code: http://msdn2.microsoft.com/en-us/library/w7wtt64b.aspx If you decide not to use the asynch pattern (BeginReceive/EndReceive), you need to check more than just Available -- as you've seen, it can return 0 before all the data has arrived. You need to make sure that the socket is "ready for reading" to know whether the 0 from Available is "genuine." You can do this with the Poll (or Select) method. But using the asynch pattern will make your code much more scalable, as you otherwise won't be easily able to handle multiple clients at once (unless you use multiple threads). Good luck...
