SUMMARY
=======

You should know how to use the Internet Database Connector (IDC) in order to use
the HTTP environment variables. These variables are returned to a HTX file or
can be used as variables in the IDC SQLStatement: command line.

MORE INFORMATION
================

Syntax
------

Below is the proper syntax for the available variables. This requires the use of
.HTM, .IDC, and .HTX files.

The HTM document should contain a FORM with a Submit button. The Action should
launch the .IDC file and its Method equal to POST.

The IDC file, for this purpose, should be fully functional. However, it does not
have to return any data from your DSN. In addition, this is where you place the
reference for the HTX file.

The HTX file is where you will place the variables.

Variable Format

the version of Internet Information Server (IIS) you are using. All variables
must be in upper case.
