I have built a file server in Java and I’m having difficulties with understanding

  • 0

I have built a file server in Java and I’m having difficulties with understanding when I should start serving the file data. As you can see below are two different client requests. Some provide two request and I’m not sure when I should start serving the data and when I should “ignore”.

Client #1:

    If you’re trying to serve audio or video it’s likely that the client is trying to leverage HTTP’s Range header. The Range header allows features like skipping to the middle of an audio/video stream, scrubbing, etc. Desktop browsers often issue a couple of requests, one to discover if the Range header is supported, and a further request to actually begin streaming content. As long as your server can handle the client terminating socket connections you’re probably safe to start streaming content for each connection.

    If you’re interested you could take a look at Brisket – it’s a lightweight, Java-based HTTP server with Range header support.
