The example should be named something more specific than html-rewriter, as it is likely that we will add other examples for the html-rewriter in the future. Maybe something script-tag-injection-html-rewriter?
To show a more complete example of a passthrough request, should the example pass request/response headers through? If you add this, please ensure that it removes "unsafe" request and response headers.
Let me know If there are additional changes or items you'd like added.
