Topic: Dereference environment variables in apache

[grafman]

I have a 3rd party module that creates an environment variable in apache. I would like to know if there is a way to use that variable as the value of another one as in:

SetEnv NEWVAR OLDVAR

We have a ton of perl scripts that use a key that the 3rd party had for a long time. Now they've changed it and we don't want to change all of our perl code and would rather not use a universal include either.

Any assistance appreciated.

Thanks

You need to load mod_env.

Syntax: SetEnv env-variable value

SetEnv SPECIAL_PATH /foo/bin

For more details see the docs

Thank you for the answer, however, your it doesn't address the question I'm asking.

I have someone else's module that supplies a variable and I need to change the key name. So using your example the module would give me:

SetEnv SPECIAL_PATH /foo/bin

Now I need to "dereference" SPECIAL_PATH to get to /foo/bin in order to set a new variable name with the same value as SPECIAL_PATH:

SetEnv NEW_SPECIAL_PATH SPECIAL_PATH

giving NEW_SPECIAL_PATH the value of /foo/bin.
