HTTP Webserver with SOCKETS

[volang]

This issue probably applies to HTTP but someone may have experienced something similar when programming a web server with c++. So I give it a try here.

In a project I'm trying to send a file(mp4/video) in a http response. I'm sending all data at once for now and trying to figure out what's happening.

The problem I've encountered is that the browser(IE) SOMETIMES aborts/close connection after it sends the first request for a resource, which makes my send attempt invalid. It doesn't matter if I send() or recv() after the request, both returns error code: 10054.


This is the conversation. The second attempt works(all bytes are sent as you can see) and I can play the file in the browser.

It would help if you didn't use multiple posts while discussing a single problem.

[volang]

Sure. I'll think about that. Now that you're here... Any thoughts?

10054 means the socket is closed.

The only method I can think of to try to work out why the connection was closed is to record the session (with Wireshark), but you'll need to learn a little more to understand what it records, and a little about Wireshark to get useful information from that.
