Creating expiring links to S3 or Cloudfront hosted content with ASP .Net

Question

Anyone have an example of creating a signed URL with an expiration using ASP .Net? I'm exploring using LitS3 or ThreeSharp in my project, and have not seen any specific methods to do this in either of those projects. Thanks.

Answer 1

Found this (mentioned in this thread in the AWS discussion forums) class library for generating signed URLs in Amazon S3. If anyone has any additional suggestions/methods to try, let me know.

Edit: ThreeSharp has the functionality I was looking for. From the ThreeSharpConsoleSample app:

      using (UrlGetRequest request = new UrlGetRequest("mytestbucket", "mytestfile.txt"))
            {
                request.ExpiresIn = 60 * 10000;
                using (UrlGetResponse response = service.UrlGet(request))
                {
                    Console.WriteLine("Try this url in your web browser (it will only work for 60 seconds)\n");
                    string url = response.StreamResponseToString();
                    Console.WriteLine(url);
                }
            }
            Console.WriteLine("\npress enter >");
            Console.ReadLine();
