Trailers() returns the headers that were set by the handler after the headers were written "to the wire" (in this case HeaderMap) and that were also specified in a proper header called "Trailer". Neither HeaderMap or trailerMap (used for Trailers()) are manipulated by the handler code, instead a third stagingMap is given to the handler. This avoid a reference kept by handler to affect the recorded results. If a handler just modify the header but doesn't call any Write or Flush method from ResponseWriter (or Flusher) interface, HeaderMap will not be updated. In this case, calling Flush in the recorder is enough to get the HeaderMap filled. Fixes #14531. Fixes #8857.

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
