Expanding on my original question, although the .htaccess redirect works, I'd like to redirect to a PHP document within the same domain and have it mask the redirection.
So, what I'd like to do is take:
RewriteRule ^t/([0-9]+) http://otherdomain/tickets/$1
RewriteRule ^e/([0-9]+) http://otherdomain/entries/$1
change them to
RewriteRule ^t/([0-9]+) http://mydomain/rd.php?type=t&num=$1
RewriteRule ^e/([0-9]+) http://mydomain/rd.php?type=e&num=$1
What I need is a working "rd.php" to handle a redirected request of this nature and then generate a frame-based redirect page sending the user to http://otherdomain/
I have a version partially hacked together, but it's probably better than I refrain from posting and let someone whip one up in 30 seconds...
Thanks in advance!
