In Windows, the http.sys component rejects any incoming post requests that do not include a 'Content-Length' header

Question

How is it possible to ignore the Content-Length header validation check for incoming requests of the HTTP.sys component?

I have not found any way to ignore the Content-Length header validation check of the HTTP.sys component. It appears to be a native component that cannot be modified, which means that the validation check cannot be disabled or bypassed for incoming requests.
