A little bit of actionscript can do that.
Heres a little game you can play in a browser window on my site, but cannot
play in a browser window on any other url, or from any local hard drive:
http://jimbo.us/Games/WordSearch.html
http://jimbo.us/Games/WordSearch.swf
Does this do what you want?
Code on first frame:
protocol = _url.substr(0, _url.indexOf(":"));
if (protocol == "file") {
message = "It seems you are trying out this game on your local hard disk.
This game will only work if played on Jimbo.us - Press 'Esc' to close.";
} else if (protocol == "http") {
doubleSlash = _url.indexOf("//");
server = _url.substr(doubleSlash+2, _url.indexOf("/",
doubleSlash+2)-doubleSlash-2);
server = server.toUpperCase();
if (server.indexOf("WWW.") != -1) {
server = server.substr(server.indexOf("WWW.")+4, server.length);
}
// end if
if (server.indexOf("JIMBO.US") != -1) {
gotoAndStop(3); // this is the real 'first frame' of the content
} else {
message = "Hey Dood! This movie\'s copyrights are being infringed! A
message is being sent to the author that you have copied his work.
\nOffending website path: "+_url;
}
}
code on second frame, with a dynamic text box instance name 'message'
stop();

Subject: [osflash] SWF protection techniques
Well, I know this is an fairly old question, but I´ve never really seen
any definitive solution for this problem at all and I´m not sure there
is one. Now that my application is near deploying, I would be grateful
if anyone could point me to techniques (server and client-side) on how
could I protect them from stealing and restrict public vieweing (for
example: if I only want the SWF to be viewed inside the HTML container
- don´t allow the user to browse the swf alone, maybe putting the swf on
a non-public dir, but then I guess I would need to use a php script to
wrap the movie So the html could open it?)...
- Marcelo.
