Increase Max Header Size for Owin Hosting

I am running a Service Fabric WebAPI application that makes use of OWIN hosting.

I have run into an issue where we are getting a 400 response: HTTP Error 400. The size of the request headers is too long

Is there any way to increase the supported request header size? The request has a large jwt token in the Authentication header (20kb)? I don' see a property in the HttpConfiguration properties

Couldn't find a way to do it programatically. Ended up setting reg keys to increase the max header size.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters MaxRequestBytes and MaxFieldLength
