Hi,

Thanks for looking into my question.

I have two scenarios where I want to stream WMA files.

#1: I have all DRM protected WMA files on my web site. My server has both
WMS and IIS. The user is allowed to select a couple songs on web pages. I
need to stream those selected files. How we can create the dynamic playlist?
I have implemented my website in ASPX.

All my WMA files are saved with some random name on my server. When the user
requests for the files (the user also can download the files by paying us),
then I am just re-naming the file name and sending it to the client as
downloadable file. How we can hide the file names/locations from ASX
file/from user?

#2: I have low quality WMA files, which are not DRM protected. The scenario
is exactly same as above. I want to hide the file names/locations from the
users, so that they can not download them directly!

Please help me with your suggestions!

Thanks,
Sasidhar

The server has DOM methods for creating the WSX playlist (XML, well,
specifically SMIL2.0 with MS extensions).

So with the example code at the bottom of this page
http://msdn2.microsoft.com/en-us/library/ms751214.aspx
you should be able to create the DOM and all necessary elements /
attributes as normal.

You can use a server-side playlist which the ASX references, and set
the mediaName attribute on the WSX media element. That will also send
the name alias instead of the media filename when logging occurs, so
it should prevent sniffing of the logging packet
