Many of these environment variables (though not all) are available to other scripting languages running on the Sambar Server, though they are called differently. For example, RCEremote_addr is the same as $ENV{'REMOTE_ADDR'} in PERL. Conversely, some variables that are available to other languages are not available to Sambar scripts; $ENV{'PATH'}
Noteworthy; many other environment variables exist on the Sambar Server which are not listed here due to their obscure usefulness or recent development (such as MAIL variables).

What other environment variables are available to Sambar Scripting and/or CGIs ?

The environment of the user and machine on which the server is running is available. (i.e. 'setenv','printenv')
In addition, any other "unexpected" HTTP headers sent by the browser in the request (prepended with 'HTTP_')
