How to convert URLs in pdf doc to a clickable Hyperlink ?

[Wolfgang Meister]

Assume I have a *.pdf document which contains URLs like

http://www.mydomain.com/mypage.html

These URLs are currently NOT clickable. But as far as I know there is a method to make them active.
Read: If I (double-)click on them the target page is loaded into the (default) browser.

Is there a way to convert these URLs in a pdf document (afterwards in a second step)
into an clickable hyperlink ?

Or is this only possible at first creation time of a pdf document
(e.g. when its printed from internet explorer) ?

Assuming Acrobat Reader 7.0 - go to Edit...Preferences...General. Check the
box by "Automatically detect URLs from text", click Okay.
