Multi-OPs should work without any script code, using
the Apache rewrite engine. I have not fully tested this
in a world but from the parts I tested it should work.

It might not work with 2.2 browsers though.

This example is assuming your old object path is on /obj
of your own server and you want to use 2 additional paths
now, the one from AW and the one from AWGate.

- Setup ----------------------------------------

1. Create a new empty directory /newobj on your server.

2. Create a text file (notepad) with these lines :

RewriteEngine On
RewriteBase  /newobj

RewriteRule  ^(.*)/(A)/(.*)$  http://objects.activeworlds.com/aw/$1/$3     [S=10]
RewriteRule  ^(.*)/(B)/(.*)$  http://objects.activeworlds.com/awgate/$1/$3 [S=10]

RewriteRule  ^(.*)$   /obj/$1

3. Rename the file you just created to .htaccess

4. Upload this file to /newobj/.htaccess, make sure it is not
   .htaccess.txt but just .htaccess !
   Upload with FTP set to ASCII transfer (Text mode) !

5. Put www.yourserver.dom/newobj into your world OP option

- Using ----------------------------------------

In your object attribute dialog, you just specify your
own models as usual :

sign1

If you want a sign from the AW path you write :

A/sign1

If you want a sign from AWGate :

B/sign1
