This morning, one of my friends emailed me this screen grab of Yahoo! Mail. Judging by the error, it looks like they're using Zend on IIS and they haven't properly setup their ErrorController so that it logs to something other than the page...

Here's the full error:
Fatal error: Uncaught exception 'Zend_Controller_Dispatcher_Exception' with message 'Invalid controller specified (st)' in C:\wwwroot\library\Zend\Controller\Dispatcher\Standard.php:193 Stack trace: #0 C:\wwwroot\library\Zend\Controller\Front.php(911): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #1 C:\wwwroot\index.php(34): Zend_Controller_Front->dispatch() #2 {main} thrown in C:\wwwroot\library\Zend\Controller\Dispatcher\Standard.php on line 193

Nice one!
Yahoo using IIS ?? Thats something new.
Signs perhaps they are hinting to Microsoft that they are ready for a deal and transition to MS platform if they increase their offer.
It will be a sad day though when the becomes a reality.
“Yahoo Using Zend?”
Why not? They already have Rasmus and so…
