In the factorio-forum I made many articles, that include pics from factorio.com. Most pictures on factorio.com are outsourced to some amazon-cloud. This is useful, cause this spares a lot of traffic.
So the urls to those pics look like so:
http://eu2.factorio.com/assets/img/blog ... eboard.jpg (taken from https://www.factorio.com/blog/post/fff-74 )
You see the "eu2". That is the problem, cause this can change with time!
This make this URL break when they add, remove, change some amazon-cloud. And my pic is gone: Looks like so:
http://eu5.factorio.com/assets/img/blog ... eboard.jpg
Universal resource locators should not change over space and time. They are somehow "static".
So, normally this problem that you link resources to a server, that can change it's name is solved either by some kind of service, which know the current "true" URL of that resource and forwards the browser to this target. So the URL can keep static but it needs always to be forwarded. The added advantage of this is, that you have an about count of how often that resource is called without looking into the cloud-servers and you keep at every time the control to resource.
Also a useful technique: An X-unclouded-source-url:-Header (I just invented that, maybe, there are better names) in the header of the above linked pic that provides such a "real" URL.
And there are of course many other techniques, the point is: you need to do something.
PS: So, without going deeper into this and into how amazon-cloud works: Does anybody already know what I need to write instead, to have a permanent URL to this resource (the pic)?
