Subject Re: [users@httpd] Re-use of a Setenv directive
Date Wed, 20 Oct 2010 13:43:44 GMT
Hello Dave,

thanks for your help.

In fact, I just want to define BASE_PATH in order to re-use it in PATHS.
PATHS contains several times BASE_PATH and I would like to change 
BASE_PATH value once instead of several times in PATHS.
