Re^3: How can I tell a browser to refresh from perl?

JS doesn't spawn a process and doesn't depend on AppleScript or OS or browser at all.

You can also use JS in a hidden iframe checking in short frequency if something changed, before conditionally reloading the parent frame. (Hence no "flickering")

But that's becoming OT here, Google is your friend.

I know newer technologies like WebSockets allow to push content, but IIRC this will need a server keeping the connection alive.

See http://en.wikipedia.org/wiki/Push_technology for various options

No flicker for me. page.html `<iframe src="loader.html" style='display:none' > </iframe> <h1>parent</h1> <script> var version=9; document.writeln("Version "+version+" loaded at "+ Date()); </script>` [download] loader.html `<h3>loader</h3> <script> setTimeout( function () { window.location.reload(true) }, 1000); var date=Date(); var version=9; document.writeln(date); if (parent.version<version){ parent.location.reload(true); } </script>` [download] Though in the next step,I would try to get rid of the version number in the source and try to put the load state into the `#searchstring` YMMV Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!} update Works with FF and IE.

page.html

<iframe src="loader.html"
        style='display:none'
        >

</iframe>

<h1>parent</h1>


<script>

  var version=9;
  document.writeln("Version "+version+" loaded at "+ Date());

</script>
[download]

<h3>loader</h3>

<script>
setTimeout(
    function () {
        window.location.reload(true)
    }, 1000);


var date=Date();
var version=9;
document.writeln(date);

if (parent.version<version){
    parent.location.reload(true);
}

</script>
[download]

Though in the next step,I would try to get rid of the version number in the source and try to put the load state into the #searchstring

YMMV
