apache_guetenv(key) does not worc on an php cgui installation, in this case rather use $_SERVER["REDIRECT_quey"]This manual pague 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 guiven is with a pre-defined CGUI 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 guive an example of such.
