Super Noob redirect question

How can I redirect all page requests from one domain / subdomain to the analogous page on another domain / subdomain? For example, I'd like a request to

www.domain1.com/dir/page1.htm

to go to

www.domain2.com/dir/page1.htm

alternatively, if I could make

subdomain1.domain1.com/dir/page1

go to

subdomain2.domain1.com/dir/page1

That would work just as well.

Note that I have complete control over both domains; I'm simply changing domains and don't want to lose any existing traffic. Is there an .htaccess answer here somewhere?

im sure you can put a simple redirect script in all the folders, which should have the link you would like to redirect to...

theres a simple script in php available, type 'domain redirect script' in google! you will find it.. if not look here too.. its around BHW somewhere!

hey... check this page out.

The problem is, I have several hundred web pages. It doesn't make sense to do one at a time. -e-
