is this possible with php or javascript?

[philosophia]

i'd like to set up a redirection page.
one of the database apps on my server will be moving to a different machine, so the url will be changing. i want to put a
php or js redirection page in this folder on the server that

-will say something like 'this site has moved, you'll be automatically redirected to the new site in 10 seconds', then redirect them there

here's where it gets tricky

-i want the redirection to cover any page within the directory where the site used to reside, so regardless of which page within the database app's folder the user is trying to get to, he'll be redirected to the site's new location

-this will probably be the most difficult - if it's at all possible, if a user is trying to get to

http://my.oldlocation.com/dynamicpage.php?variable=var&newvar=var&thirdvar=three

i'd like the redirection script to replace the string 'my.oldlocation.com' with 'my.newlocation.com' in the url string and then redirect them to

http://my.newlocation.com/dynamicpage.php?variable=var&newvar=var&thirdvar=three

any comments and suggestions are welcome. if i could get either of the last two items going with this script that would be great

thanks again

If you are using Apache, then you can use RedirectMatch or Redirect directives to do the job. OR you can use mod_rewrite to rewrite the url and redirect without the having the request go through to php. Take a look at Apache's documentation for more detail!
