Php Super Widget
The Super Widget is a crawler that will can return useful info including <Meta> tags where present or read and output a selectable amount of bytes from the files it can open.
It was home built using PHP Version 4.0.2, on a win95 box running Apache 1.3.11 (Win32 Binary).
It should be fairy easy for you to add your own tweeks even if your a php beginner (like me).
Plans are also afoot to build an ASP / VB script version.
Here's the code. save it as 'super_widget.php'.
