Matthew Holt d93e027e01 reverseproxy: Reuse buffered request body even if partially drained

 2024-04-22 15:22:50 -06:00
Matthew Holt 613d544a47 reverseproxy: Accept EOF when buffering 
Before this change, a read of size (let's say) < 10, into a buffer of size 10, will return EOF because we're using CopyN to limit to the size of the buffer. That resulted in the body being read from later, which should only happen if it couldn't fit in the buffer.

With this change, the body is properly NOT set when it can all fit in the buffer.
