Conditional SetEnv

set environment variable if value doesn't exist

Thanks in advance for any help anyone can provide.

Is it possible to check for the existence of an environment variable before setting a new one? And only setting the new one if it hasn't already been set?

I'm a programmer, and I have an apache set up at home, and my project uses an htaccess file to set the env. I'm setting my own in my vhost file, and I want to modify the htaccess to check for this value, and only set its own if the server hasn't set one.

I'm pretty new to htaccess syntax.

Thanks!

I actually found the solution with a little more aggressive googling. For anyone who's interested, I posted the solution on my company blog.
