You could hold the swfs in a database (or in some datastore only
accessible to the server), then serve out the swfs through Java or PHP
(or any other serverside language). Authenticate each map request with
a username / password in the query string. If you wanted to prevent
that username / password from being seen (by people watching the
line), use HTTPS.

One way is to use the _url property, which will point to the .swf's
location on the file system, then just have each map check if it's
residing at the proper url.  If it is allow the map to be view and if
not don't display anything.

Subject: [Flashcoders] How to hide SWF Assets from Internet users

Hello All,

I have an intense situation right now, and I must come up with an answer
ASAP.

I wrote a map viewer application for my client, in which my viewer can
load .swf Vector Maps from a predetermined directory on the server.
>From within my viewer, the users can perform drill-down queries, by
selecting contents of multiple dropdown boxes - State, Region, then Lake
Name.  Paid subscribers, have full access to their maps - but it's
imperative that they can ONLY view these maps from within the viewer
app.

Since the Flash Map Viewer, needs to retrieve these maps from the server
using a public URL (unless I am overlooking something), how can I hide
these maps from the world - if the outside users are able to figure out
which path to type into their browser, and snatch up maps?

I know that server-side scripts, can access local resources - like
"D:\Documents", etc. - but once the Map Viewer is running from a Remote
Browser, how can I bury these maps under some type of file system that
is not directly accessible by the outside world (but only through the
Map Viewer app)???

Also, once the user views a particular map, how can I prevent the
map.swf file from being Cached on their hard drive?

If any of you could help me out regarding this, I'd be very
appreciative.

Thanks,

Mike
