# Apache module mod_env

This module is contained in the `mod_env.c` file, and is not compiled in by default. It provides for passing environment variables to CGI/SSI scripts.

## Summary

This module allows Apache's CGI and SSI environment to inherit environment variables from the shell which invoked the httpd process. CERN webservers are able to do this, so this module is especially useful to webadmins who wish to migrate from CERN to Apache without rewriting all their scripts
