Bug 11609

Hi,
 
I'm currently tried to use this taglibs, which covers all my needs. But I found 
out, that this tags doesn't refresh after the time which those scrapes will be 
cached.
So I had a deeper look into the source and found the problem in the PageData 
class.
The method "scrapePage" connects at the first call to the server and fetches 
the data correct. But this doesn't work at the second time, when the cache time 
is elapsed. The reasen for this is because the variable scraping will then not 
be set to false.
You see my change at the end which works fine.
 
I hope this will help you
Stefan
