Gated incoming requests

[aspnet-hello]

In Orchard CMS, there was a feature where multiple incoming requests will block until the response for the first one is generated and is used to satisfy all waiting requests. Will need to investigate how this can be supported, either within the middleware or by the user given the available extensibility points.

@sebastienros How much do you want this? Would you like to talk design, and possibly send a PR?

/cc @rynowak as he was key in the decision to have it in tag helpers.

It's unlikely we'll implement this unless there's more demand for this issue.
