The requests distributed to the POST request-forwarding worker must fulfill the following conditions:

Conditions of the requests distributed to the POST request-forwarding worker

• The request method is POST.
• The request has a Content-Length header (body data is not in chunk format).
• The value of the Content-Length header of the request is less than the POST data size set in the worker.

A request that does not fulfill even one of these conditions is distributed to the default worker. If the default worker is not set, an error occurs and an error with error status code 400 is returned.
