#VarENV ---+++ ENV{"varname"} -- inspect the value of an environment variable * Returns the current value of the environment variable in the CGI (Common Gateway Interface) environment. This is the environment that the CommandAndCGIScripts are running in. * *Note:* For security reasons, only those environment variables whose names match the regular expression in ={AccessibleENV}= in the *Security Settings/Miscellaneous* section of =configure= can be displayed. Any other variable will just be shown as an empty string, irrespective of its real value. * Example: =%<nop>ENV{MOD_PERL}%= displays as: %ENV{MOD_PERL}% * If an environment variable is undefined (as against being set to the empty string) it will be returned as =not set=. * Related: [[%IF{"'%INCLUDINGTOPIC%'='Macros'" then="#"}%VarHTTPHOST][HTTP_HOST]], [[%IF{"'%INCLUDINGTOPIC%'='Macros'" then="#"}%VarREMOTEADDR][REMOTE_ADDR]], [[%IF{"'%INCLUDINGTOPIC%'='Macros'" then="#"}%VarREMOTEPORT][REMOTE_PORT]], [[%IF{"'%INCLUDINGTOPIC%'='Macros'" then="#"}%VarREMOTEUSER][REMOTE_USER]]
