[go-nuts] Serve static files and allow parial content

some additional information i forgot to mention. The whole thing happens
over ssl, and it works with self signed certificates, but not, when I sign
it by startcom, cacertificates etc. It also works all good, when in
inspector I disable caching in chrome

Can you share code?
Have you debugged with wireshark, what requests happen, what are the responses... Etc?
Even the server log could help.

You point on SDL: does it work without SSL?

So please try to narrow the problem.

The setup is pretty basic. This is the Path in Main() that is supposed to
serve the Files.
http.Handle("/data/", auth.Chkauth(view.HandlerToHandleFunc(http.StripPrefix
("/data/", http.FileServer(http.Dir("./data/"))))))

The html-Template works like this.
<video width="1280" height="720" preload="auto" controls><source src=
"{{$v.Source}}" type="video/webm"> {{if $v.Subpath}}<track src=
"{{$v.Subpath}}" kind="subtitle" src="de-DE" label="german">{{end}}
  Your browser does not support the video tag.</video>

I play a video in chrome and get...

Now when I try to seek in the video and jump to somewhere in the middle.

This should be a really basic setup shouldn't it?

I Just checked the Rest. As i said, it works, when the certificate for ssl
is selfsigned. It works, when I disable caching in chrome which would send
Cache-control: nocache in request and it works, if I don't use SSL at all

I did some additional testing over the past few hours. And this is what I found.

Everything works on local machine.
When I run it on a remote machine it doesn't. Even without SSL the connection breaks when seeking the video.
The response headers are always the same.
I switched from http.FileServer so http.ServeFiles but that didn't change anything.
I tested on two different machines. One Debian testing and one arch Linux. Both didn't work out.
