Limit Http Requests

[melanie.ernst]

Hi all,

I've read a couple of months ago that there is a limit regarding the http requests. Which means the user is only allowed to send e.g. 500 requests a day.

Is this true? Is there really a limit?

It would help a lot if you mentioned what you are talking about. Your question does not make much sense in the context of the desktop Revit API, which is the one and only topic of this discussion forum. Maybe you are referring to the Autodesk Platform Services, formerly known as Forge. In that case, please direct your question to the official APS help channels:

Hey, sorry for the short question! 😅

So basically what I am trying to do, is to create a plugin in Revit that gets some information from a server via http request. E.g. the user needs to log in via the plugin and types in username/password. this will be sent to the server for authentication via http.

So my question: how many http request can a user send? is there any limitation?

I am not aware of any such limit, and I doubt that Revit or its API impose any such thing either.

I think it depends on your physical environment.

.NET sends http requests by ThreadPool which has a max thread count. You can check this capacity by using ThreadPool.GetAvailableThreads(Int32, Int32) Method or ThreadPool.GetMaxThreads(Int32, Int32) Method .

ThreadPool has a queue internally which means your can spawn as many requests as you can within the limitation of the OS and hardware and the ThreadPool will consume them when there are available threads anytime.
