how to check the address in the location bar?
i.e. <!-- m --><a class="postlink" href="http://www.domain.com?id=454hd&session=sjfdj7&place=ny">http://www.domain.com?id=454hd&session=sjfdj7&place=ny</a><!-- m -->.
How to check whether a particular one is empty? If a viewer manipulates and leaves 'id' blank,then it goes to another page. How to do that?
Thanks in advance
