Rate limiting / throttling of response downloads

[Kaliumhexacyanoferrat]

As the developer of a web application, I would like to be able to throttle the bandwidth of certain responses, so that my app stays responsive on slow connections.

Example

var limit = Throttle.Connection()
                    .Limit(50); // kb/s

var app = Layout.Create()
                 .Add("myfile.zip", Download.From(...).Add(limit));

Hints

The concern could wrap the IResponseContent provided by the inner handler into a limited response content which passes a rate limited Stream instance into the inner response content.

Acceptance criteria

• The functionality is implemented in a new module (such as GenHTTP.Modules.RateLimiting)
• The functionality is implemented as an IConcern
• Limit can be specified either per connection or as a total limit for all connections
• Limits can be specified on a reasonable scale (such as kb/s)
• The functionality introduces as few shared locks as possible
• There are acceptance tests to ensure the implemented functionality
