[Q] Howto go directly to a URL?

I have written a very straightforward user login script. Once the user successfully logs in, I would like my PHP script to take him directly to the home page. I know this sounds simple, but the only solution I've found is a function called do_html_url() from Welling and Thompson's book (see http://www.cs.indiana.edu/classes/a348/fall2001/labs/php9/do_html_url.html). When this function is invoked the user is dispatched to an intermediate web page on which is presented a link that, when clicked, will take the user to the intended page. Can I avoid that intermediate step, somehow? When my script logs in the user, how to I write the code that dispatches directly to the home page? Thanks, Cheers, Michael
