Summary

    This module allows for control of internal environment variables that
    are used by various Apache HTTP Server modules. These variables are also
    provided to CGI scripts as native system environment variables, and available
    for use in SSI pages. Environment variables may be passed from the shell
    which invoked the httpd process. Alternatively,
    environment variables may be set or unset within the configuration process.

PassEnv Directive

Description:Passes environment variables from the shell
Syntax:PassEnv env-variable [env-variable]
...
Context:server config, virtual host, directory, .htaccess
Override:FileInfo
Status:Base
Module:mod_env

    Specifies one or more native system environment variables to make available
    as internal environment variables, which are available to Apache HTTP Server modules
    as well as propagated to CGI scripts and SSI pages. Values come from the
    native OS environment of the shell which invoked the
    httpd process.

    ExamplePassEnv LD_LIBRARY_PATH




SetEnv Directive

Description:Sets environment variables
Syntax:SetEnv env-variable [value]
Context:server config, virtual host, directory, .htaccess
Override:FileInfo
Status:Base
Module:mod_env

    Sets an internal environment variable, which is then available to Apache
    HTTP Server modules, and passed on to CGI scripts and SSI pages.

    ExampleSetEnv SPECIAL_PATH /foo/bin

 
     If you omit the value argument, the variable is set to
    an empty string.

    The internal environment variables set by this directive are set
    after most early request processing directives are run, such as access
    control and URI-to-filename mapping.  If the environment variable you're
    setting is meant as input into this early phase of processing such as the
    RewriteRule directive, you should
    instead set the environment variable with
    SetEnvIf.
