When using Content-Encoding: gzip, Content-Length is the compressed, post-gzip-encoding size.
I want to add a header for the uncompressed, pre-gzip-encoding size. An embedded application will read this and preallocate a correctly sized buffer for the decoded data up front.
What should this header be? Is there any convention I can follow? Or shall I choose something kinda arbitrary, like X-Decoded-Content-Length?
