I am working on an application where I need to send a streamed http 1.1 request to a server that includes an HTTP trailer. I know that setting the trailer header on a request is easy with most client implementations, but I have not been able to add the trailer to the end of the request body. I was wondering if any popular clients do support this feature?

I tried using the HttpURLConnection class, but it does not support trailer headers on a streamed http 1.1 request.
