We have a static HTML template that contains a text box form control. This template is used by a CAM application to generate job setup instructions for CNC machines. Once the template is used to generate the html, then the programmer will type text instructions into the form control, but when the html file is saved the contents of that control are not saved.
The template and a sample generated html file are included here in the project proposal. The cfg file is the template where everything will need to be stored.
This has to be completely self contained in the html - it cannot call a server side script.
