Question

When a new http request comes in, will a new instance of sinatra be started, e.g. has sinatra to be initialized, or is just the method of a previous instance (the corresponding get/post method/route) of sinatra be called?
Thank you for any documentation links, i wasn’t able to find any.

It would also be interesting if that behavior is dependent on the deployment type – WEBrick/Passenger etc

Answer 1

A new class is created for every request. However, this is not done by Rack. This is a feature of Sinatra. If you want to dig into the details: The instance is not actually created with Sinatra::Application.new but with Sinatra::Application.prototype.dup, see Sinatra::Base#call for the code.
