Q: IIS 7 how to customize the security model using c# We have migrated a legacy streaming server to Wowza. As well as streaming on that server we need to have some mobile handsets have their delivery of mp4 files to be handled by IIS (7) HTTP straight download.
I need to replicate the security model that we had before based on our own key within the url parameters. (This I have done in Wowza also now). Nothing built-in in IIS would match our needs. So what I need to do is create a plugin for IIS that can see the URL of all incoming requests and either accept or deny them. 
Can anyone point me into the right direction as to the API / plugin I should be interested in?
