We are working on hosting recorded ARF files for user access on our web server. The archive of ARF files we have is too large to be kept on Webex, so we need to download and make it accessible from our server. The Webex has a nice feature we want to replicate: when user selects URL of the ARF recording, it  automatically launches network recording player installed on user's PC and doesn't allow saving the ARF file. From what I could gather by looking at the source code, the URL of the recording is linked to a Java script that launches user's player installed on his PC and closes the browser window so use can't find the link to download the ARF file. If anyone has a sample code or can point me in the right direction, it would be great.

This almost works. The Webex Player starts properly, but then throws "Webex Player cannot open a file of this type". It looks like this php script launches WRF player, not ARF.
