[Jprogramming] How can I auto-refresh a JHS app page?

[Ian Clark]

Suppose I am a JHS coder, working with the J session (the jijx page), and
have written an app called "message" (say). This generates a page of data
in response to the URL:

http://localhost:65001/message

which I choose to display in a separate browser window. Let's call it the
message window.

If I execute some phrase in jijx which changes the content of the message
window, then in the normal course of things I would need to manually reload
the page in order to see the altered data. For example (in Safari) by
activating the message window and clicking the symbol: "Reload this page".

How can I write a verb (to be executed in jijx) which refreshes the message
window without having to do that?
