This manual page is unclear as to whether it will fetch Apache configuration environment variables set by "SetEnv" (including "SetEnvIf[NoCase]" or "BrowserMatch" e.g.) as the only example given is with a pre-defined CGI interface variable (which is also available via the $_SERVER[] array). If custom Apache runtime configuration variables are indeed fetchable via this interface, let's say so or give an example of such.
