An os_input_hidden is a hidden name/value pair within an os_form . An os_input_hidden is typically used to maintain state information across multiple query-response exchanges between a browser and a CGI program.

The name and value of an os_input_hidden are specified in the constructor and can be modified through the name() and value() member functions.

An os_input_hidden element is not rendered by the browser, and its value cannot be modified by the user. The name/value pair is transmitted with those of the other input elements within the containing os_form when the os_form is submitted.
