This optional file is a "template" for use with the HTTP
server.
When the server receives a request whose URL begins with
"/exec?cmd=", it passes the command to XRPi for
execution, and serves a "template" page displaying the
response to the command. The template serves as a wrapper for
the text.
If you wish to override XRPi's inbuilt HTML template, edit the
file EXEC.HTM, which was supplied with the installation
package, and put it in the XRPi working directory. This file
is not placed within the HTTP directory tree because it is not
intended to be served in the normal way.
If EXEC.HTM exists, the server will serve it in place of the
inbuilt template, replacing the <TEXT> tag with the result of
the executed command. EXEC.HTM does not currently support
Server Side Includes.
