No cache on embedded objects

[Dave]

I have an ASP page with the "no cache" command. I know the ASP file is not
being cached. But the flash file that is embedded in the ASP page is
repeatedly cached by my browser.
Anyone discover a sure-fire method to prevent caching of embedded files?

The nocache command in the ASP file applies only to the ASP file. You can
set this server-wide in IIS' settings (see http://www.aspfaq.com/2022). Or
you can use ASP to append a random number to the src of the movie, e.g.

<param name=movie value='somefile.swf?r=<%=someRandomNumber%>'>

Or, you can rename the Flash movie.

Is the Flash file changing enough that this is actually a problem?

The file will be changed frquently. Once I have an example running, the
windows to insert text will grow. So I do have to have current
information transferred back to the Flash file.

Currently, it will be multiple textboxes importing text from a .txt
file. The textboxes can then be updated and resaved to the .txt file.

Aaron,

I did plug in the code you provided into the ASP page code. The Flash
file is still caching.
Also tried Actionscript code, within the Flash file, to force the movie to
call upon the server to generate a random variable and then retrieve the
variable in hopes that it would be forced to refresh with each visit. No go.

Does vbScript have a way of forcing an embedded file to reload from the
server?

The Flash file, or the text file? Have you considered using a database?
