Ian, By resources, I meant google. The phrase that will get you started is 'javascript shared local storage'. A search of the JHS scripts will show a few simple places where it is currently used. But there is no current use of the very interesting event triggers. On Tue, Sep 5, 2017 at 11:35 PM,

Ian (your JHS question), There is a facility in javascript in the browser called shared memory. JHS uses this in a very limited way, but I have always wanted to revisit it to see what else could be done. One page setting shared memory can trigger an event in the javascript of the other page. Is

@Raul, Refresh: 3 …works a treat. Besides giving a conspicuous indication in the Safari toolbar that the "animated" window is alive and kicking. All no doubt horribly inefficient. But good enough in the short term for my experiments. Mac:Activity Monitor does show the resource usage of both

For server sent events, you'd need to remove the Connection: Close http header and replace it with a Content-Length: nnn header. You'd also need to jhs to leave the socket open so that the events can be sent using that same connection. This would require some significant restructuring of jhs, to

It's probably worth noting that a meta refresh tag - see http://blooberry.com/indexdot/html/tagpages/m/meta.htm for some docs - is one that would look like this: http://localhost:65001/message; /> But what this is doing, in essence, is creating an http header that would look like this: Refresh:

Depending on your requirements (the browser used by users), you could consider Server-Sent Events, an alternative to websockets, but they are not supported in IE neither (yet?) in Edge. In HTML5, Server-Sent Events are probably what you need. Have a look at the following with a clock example in

That's pretty much it. The browser is in control here, and jijx is only indirectly in control as a result. Probably the simplest would be to put something like Refresh: 3 in the http headers in your MYTEMPLATE (before the first blank line). But I haven't tested that - I probably need to upgrade
