WWWForm.data

Description

(Read Only) The raw data to pass as the POST request body when sending the form.

Usually, you just pass the WWWForm object directly to the WWW constructor, but you will need this variable if you want to change the request headers sent to the web server.

Additional resources: headers variable.

        string url = "www.myurl.com";

        // Add a custom header to the request.
        // In this case a basic authentication to access a password protected resource.
