Multiple Ruby versions at the same time ?

[thbar]

Hello,

I have two old Rails applications that rely on ruby 1.8.4 (they should be upgraded later) on one LiteSpeed instance - cannot be upgraded right now.

I need to deploy a brand new Rails 2.2.2 on the same server, most likely with Ruby 1.8.6.

Is there a way I can specify a different Ruby version for both ? (I've seen that I can modify the PATH at the server level, not sure I can do it at the application level ?).

thank you!
