Well, the previous solution didn't work. Try calling:
$wgOut->enableClientCache(false);
In your extension code. You have to declare $wgOut global. It seems to work now. I guess, we have to keep in mind that this will create extra work on the server while serving the pages we set the caching off.

Not sure about that. A normal refresh looks like it really gets the page from the server. I can refresh my page containing the extension doing a hard refresh. In Firefox (on windoze), it's ctrl+f5 or ctrl+refresh button (not sure of the latter), it should be a similar combination in IE, too.
In SpecialRecentChanges.php, I see:
$wgOut->setSquidMaxage( 10 ); if( $s->lastmod && $wgOut->checkLastModified( $s->lastmod ) ){ # Client cache fresh and headers sent, nothing more to do. return; }I'll try the first line to see if it works.

I don't think it has anything to do with the browser. It's a server issue. I *am* retrieving the page from the server -- I can see the hit in my logs, and I can see the time it takes to generate the page. (If it's coming from a cache, why does it take so long, anyway? Seems to be the worst of both worlds! :-)

I have the same problem. There should a HTTP header to invalidate caches so that the browser retrieves the page from the server. I guess, we can look at the code of recent changes and OutputPage.php to find out what needs to be sent. Then it should be OK, I believe, to do $wgOut->whatever() in the extension code to send it.

I'm playing with extensions, but am having trouble seeing the
results.
How can I mark an article as "dirty" in an extension, so it will refresh every time?
Here's my extension, using the Unix fortune(6) command, which returns a random fortune each time, but when refreshed in a browser, I get the same one back each time. When I click "edit," I get new results, but when I refresh my browser, I do not. I even turned debugging on in
the
browser and made sure the browser cache was cleared. (It's taking enough time; it's obviously doing SOMETHING on the server.)
Another odd thing happens: if I use system() or passthru(), the fortune DOES refresh, but it prints at the top of the window, rather than inside the content area. When I tried shell_exec(), it puts the same old fortune in the content area each time!
extensions/Fortune.php
<?php $wgExtensionFunctions[] = 'wfFortune'; function wfFortune() { global $wgParser; $wgParser->setHook('fortune', 'renderFortune'); } function renderFortune($input) { $output = "<p><i>"; $output .= shell_exec('/sw/bin/fortune'); $output .= '</i></p>'; return $output; } ?>
