Fixes #35544

We have two spots to place guidance ...

  • As you said, in the HTTP context article. Are the two example cases that I provide enough?
  • In the Startup article, where we show how to set headers before the response has started.

I thought we had a remark on this subject somewhere, but I couldn't find anything when I searched.
