I have recently learned how get my Perl script to open a text file, using something like this;

($INPUT_FILE = "weeds_bgy.txt");

And I can specify a path to the file, such as;

($INPUT_FILE = "textfiles/weeds_bgy.txt");

But what I really want to do is open the file using a URL, such as

($INPUT_FILE = "http://www.domain.com/textfiles/weeds_bgy.txt");

Any help would be appreciated, even to say that's not possible.
