There is a libUrlFollowHttpRedirects command. This seems to have been  
omitted from the 2.6.1 docs. :-( You can get information here:

     http://www.lacscentre.co.uk/liburl/ 
liburldoc.html#libUrlFollowHttpRedirects

If you set this to false, a "get url" call to such a url will return  
the relevant response in "the result", like this:

  error 302 found

You could then use the libUrlLastRHHeaders function to see the full  
response from the server, for example if you needed to parse out the  
"Location:" header, and handle the redirect yourself.
