LWP::Simple getstore with absolute path not working

I am using the following line of sort in a batch file to fetch things off the network quickly and mostly I have success but if I need to indicate an absolute path in the URL, I always get a "not found" error. I have perl 5.8.x, URI.pm 1.36 and URI::URL.pm 5.03 on the XP system where did the test. Help!
