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.

Here’s what worked for me with the AWS SDK and MVC 3 (based on the answers above and what I found on http://www.ec2studio.com/articles/s3.html):

public ActionResult GetS3Object(string bucket, string key)
{
    string accessKeyID = ConfigurationManager.AppSettings["AWSAccessKey"];
    string secretAccessKeyID = ConfigurationManager.AppSettings["AWSSecretKey"];
    using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID))
        {
        GetPreSignedUrlRequest request = new GetPreSignedUrlRequest()
            .WithBucketName(bucket)
            .WithKey(key)
            .WithExpires(DateTime.Now.Add(new TimeSpan(7, 0, 0, 0)));
        return Redirect(client.GetPreSignedURL(request));
        }
}
