Since this is a mod_perl list, I'll suggets a Perl solution. Write a
PerlTransHandler that does what mod_rewrite does. You can get the query string
from $r->args and send redirect headers.
A quick example (this works, BTW):
package Apache::Redirect::Based::On::Query::String;
use Apache::Constants 'OK','REDIRECT';
use constant DEFAULT_URI => 'http://www.boston.com'; # shameless plug!
sub handler {
my $r = shift;
my %args = $r->args;
my $path = $r->uri;
# $uri holds something like 'http://www.mysite.com/news/' if the initial
# request was 'http://www.yoursite.com/news/?uri=http://www.mysite.com/'
my $uri = (($args{'uri'}) ? $args{'uri'} : DEFAULT_URI) . $path;
$r->header_out->add('Location' => $uri);
$r->status(REDIRECT);
$r->send_http_header;
return OK;
}
Set it up in httpd.conf as:
PerlTransHandler Apache::Redirect::Based::On::Query::String
