7

SYNOPSIS

9       String getEnv( String env )
10

ARGUMENTS

12       env The name of the environment variable
13

DESCRIPTION

15       Retrieves the value of an environment variable.
16
17       This is often necessary in a web application as the web server will set
18       environment variables in the program. Some of these headers are set  by
19       the  server  environment,  others  are set based on the current request
20       (and so may be trivially forged by the user's browser).
21
22
23    ua = getEnv("HTTP_USER_AGENT"); // Contents of User-Agent header
24    host = getEnv("HTTP_HOST"); // the IP address of the web server
25    user = getEnv("REMOTE_USER"); // the username under HTTP authentication
26    ip = getEnv("REMOTE_ADDR"); // the client's IP address
27
28       Environment variables are also useful for command-line programs
29
30
31    home = getEnv("HOME"); // The user's home directory on Posix systems
32    proxy = getEnv("HTTP_PROXY"); // The HTTP proxy to use for  outgoing  con‐
33   nections
34
35       If  the  environment  variable  is  not  set,  the empty String will be
36       returned.
