I think I have the solution for you problem.

Just define some kind of API which says: If there is some "global" variable set by the
USER func it doesn't get cached.

So I would do something like:

+			case 'CINT':
+				$conf['__cacheKey'] = md5(random(1, 0x7fffffff).time());
+				$c=$this->callUserFunction($conf['userFunc'],$conf,'');
+					// plugin asks for caching of the content?
+				if (intval($GLOBALS['TSFE']->CINTcachingArray[$conf['__cacheKey']]))      {
+					$content.=$c;
+					break;
+				}


So the USER function should do something like:

$GLOBALS['TSFE']->CINTcachingArray[$this->conf['__cacheKey']] = 1;

if it want's to get cached.


no changes in the core required elsewhere except that you should add the CINTcachingArray or whatever
it will get called to the tslib_fe class as an empty array.


Here my resume:
Very nice feature. We should call it MINT not CINT so it stands for MostlyINT (what stand CINT for)
and also for "MartinINT" :) :)
it would also sound somehow more refreshing !

And another proposal would be to let the CINTcacingArray be either an integer == do fully cache with site.

Or "trara" .. an array like:
array(
	'expires' => 3600*24,	// expire time in seconds from now
	'until' => time()+(3600*24),	// expire time in absoulte time
	//	both of them and whichever is first.
);

Then make some possiblity to set this return values from a "traditional" cObj like "TEXT" and you
have a solution to output for example the date of the current day on a heavy loaded server without
clearing the complete cache each day at 0:00


Even if you not have this feature it would also bring us nearer to it.
So just post the latest version with the change Wolfgang made manually included and I
will test it.




greets,
Bernhard
