    We used to set this only for packages that had manual supersource. That

    The problem is that GWT responds poorly to two .gwt.xml files in the same

### Before and after the `response` { #before-and-after-the-response }

You can add code to be run with the `request`,  before any *path operation* receives it.

And also after the `response` is generated, before returning it.

For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:
