The THTTPFormValues class is used by the TWebServerRequest class for representing any HTML form values included with an incoming web server request. When an HTML form is submitted to the web server, any form values will be available in the TWebServerRequest RequestFormValues property.
Any file uploads included as part of a multi-part HTML form submittal request will be available in the RequestContentParts property.
Please see the Using HTML Forms topic for more information on how to submit HTML forms to a server application or native server module.
