To enable the Form feature, the compile-time configuration HTTPs_CFG_FORM_EN must be set accordingly (See section Module Configuration).

Also a configuration object (HTTPs_FORM_CFG) MUST be added to the HTTP Instance configuration (See section Parameters Configuration).

For more information on HTTP Form Submission, see section Form.
