All,
Bump.
Anyone?
No, but I tried. But everything I found seems to say that such trailers are really rarely
used, and that's probably why you are not getting any echo.
I believe that initially you mentioned that you had found a perfectly good use case, but
you never explained what it was...

All,
I've got a perfect use-case for HTTP trailers but it doesn't seem
like any existing client (e.g. HttpURLConnection, HttpClient) has
support for them on the /sending/ side.
HttpURLConnection doesn't have a way (that I can see) to fetch
trailing headers, but it may just be that you have to consume the
response and then check the headers (similar to what you'd do in a
Servlet when the client actually sends trailing headers to the
server).
HttpClient allows you to get the trailing headers from a response
in a very awkward way by reading them from the ChunkedInputStream
which is buried a few levels deep, evidently.
But neither seem to have a way to actually *send* headers to the
server.
Has anyone ever actually done this from a Java-based client? I'm
currently using my own wrapper around HttpURLConnection (because
HttpClient seemed to heavy for my purposes) and it's been working
great for a few years. I'd like to support a streaming mode plus
trailer headers with it, and I'd prefer not to dump
HttpURLConnection and replace it with low-level socket work because
them I'll have to do a whole bunch of work to reproduce what
HttpURLConnection is already providing (e.g. TLS, auto-redirects,
etc.).
Any ideas from the community?
Thanks, -chris
