  Concurrent user problem Reply Contact Hi, This may be a beginner request but wondered if anyone could assist. I have created a website on my company network. The site contains basic html pages displaying a set of copyrighted images for which we only have permission for 10 users to use at any one time. Is there any way to achieve a 10 user limit with IIS? The 'Limit Number of Connections' option doesn't work this way as that seems to be the maximum number of requests made at any one time from a web browser. Any advice would be much appreciated!

  Re: Concurrent user problem Reply Contact Not natively. Beside, typical browser initiates 2 connections to web servers. To limit per user, you might want to implement it at code level and control at app level. There is one new extension http://www.iis.net/extensions/DynamicIPRestrictions which allows you to specific concurrent request per IP, that won't help you exactly and not a good deal if users are behind proxy servers.

  Re: Concurrent user problem Reply Contact You can enforce the number of users downloading the image from IIS, but how could you enforce how many users are using it?  Once a user has downloaded it, there is no way for IIS to know whether the user is still using it or not. You would need some sort of DRM to enforce the number of users using the image. Anil Ruia Senior Software Design Engineer IIS Core Server
