How to call an URL with R

How to call an URL with R

Is it possible to just call an URL from within R? I dont want to
explicitly download a file, so url(..) or download.file(..) or Rcurl may
not be applicable.
Maybe it's important to note that calling the URL will automatically
trigger a download.
The URL is
http://www.google.de/trends/trendsReport?hl=de&q=keyword&date=today%203-m&cmpt=q&content=1&export=1
Thanks!
