Plugin answer... it would seem
[1/2] from: sterling:rebol at: 11-Jun-2001 14:03
It would appear that the solution to this is to have diferent file
extensions. One is mapped to a plugin that handles the embeded stuff,
draws into the browser window, etc. The other one is an application
mapping that just runs the specified program without departing the
current web page to go to the link.
Does this sound right? Anybody know of an app that uses the same file
extension for both a plugin and helper app?
Thanks to GS Jones for the example.

Hi, Sterling,
Maybe I wasn't entirely clear. The example I sent **does** use the same
extension. That is the really neat part. Here is what I think is going on
(which may not even be worth 2 cents...):
Registry entries:
[HKEY_CLASSES_ROOT\.smi]
@="RealPlayer.SMIL.6"
Content Type
="application/smil"
[HKEY_CLASSES_ROOT\RealPlayer.SMIL.6\shell\open\command]
@="\"C:\\Program Files\\Real\\RealPlayer\\RealPlay.exe\" /m application/smil %1"
[HKEY_LOCAL_MACHINE\Software\CLASSES\MIME\Database\Content
Type\application/smil]
Extension
=".smil"
If I read this correctly, the first entry .smi maps to application/smil, and the
third catalogs a.smi amongst all the mime types. The second entry will open the
regular application
from within the windows environment or from the href tag.
It is the short snippets of javascript that I think is opening the RealPlayer
and stream embed in the browser.
Snippet that sets the stream location:
<SCRIPT LANGUAGE="JavaScript">
browser=navigator.userAgent;
stream_location http://bb1.stream.aol.com:8080/ramgen/adtag/general/live/bblive1.smi
;
</script>
Snippet that sets up the embeded object. Note the mime type.
document.write( .... <embed src="'); // starts embed
document.write(stream_location); //sets stream location
document.write('?embed" type=audio/x-pn-realaudio-plugin '); //maps to plugin
mime
document.write('console=promo height=132 width=176 autostart=true
controls=ImageWindow
PLUGINSPAGE="http://www.real.com/player/"></embed>');
(I left out the snippets that map the realplayer controls, etc)
This is the reg entry that maps the mime back to the plugin:
[HKEY_LOCAL_MACHINE\Software\CLASSES\MIME\Database\Content
Type\audio/x-pn-realaudio-plugin]
CLSID
="{CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA}"
Then for the href:
<a href="http://bb1.stream.aol.com:8080/ramgen/adtag/general/live/bblive1.smi">
Feed 1</a>
This just opens the regular app. How they keep the browser page the same, I do
not know. But they do.
So, RealPlayer has this one extension and two mime types. The javascript calls
the embeded version, which is then fed the stream location. Smi is the wrapper
info that controls streaming video stuff, if I recall correctly, maybe Carl
knows more about this.
I included the Reg Entry below for the audio/x-pn-realaudio-plugin ..... for
easy reference. Full backwards compatibility. No confusing alternate
extensions. But ... there is that blasted ActiveX ........
Cool!
No problem on not being plugin expert. REBOL is the most important thing.
Great plugin will help to rocket it to fame.
