Mixing
Set Maximum content-length Accepted
Is there a way in Rails to specify the maximum allowed content-length so that requests that exceed this value are rejected immediately?
I have a login form on my application that is the only POST available to an unauthenticated user. This has been identified as a potential vulnerability to a slow POST DoS attack. One of the mitigations is to limit the allowed request size.
I cannot seem to find the knob to turn which will allow me to automatically reject the request if the content-length exceeds a particular value.
We're using the Puma web server if that affects the answer.

Puma has two parameters actually, the number of threads and the number of workers. If we slightly change the default puma.rb, it will look like that:
workers Integer(ENV['WORKERS_NUMBER'] || 1)
max_threads_count = Integer(ENV['RAILS_MAX_THREADS'] || 1)
min_threads_count = max_threads_count
threads min_threads_count, max_threads_count
