Multi-domain site - serving different robots.txt?

[punkstjimmy]

We have a multi-domain site which uses two different site roots. We need to alter the robots.txt file for one of the domains but leave it as it is for the other. They share the same file system so if we change the one and only robots.txt it will change it for both sites.

Is there any way around this?

Thanks!

Maybe you could use htaccess rules to serve different robot files for each domain:
