Explanation:

• getFormFields(): Extracts hidden inputs from the login form.
• Set email and password: Sets the appropriate email and password values.
• Get x value: Retrieves the "x" value from the login URL for use in the correct login URL.
• Set login URL with x value: Constructs the correct login URL using the obtained "x" value.
• Set POST fields: Converts the form fields into a query string for POST.
• Change URL to login URL and set post options: Configures the Curl handle for the login request.
• Perform login: Executes the login request.

By implementing these changes, Curl can successfully log in despite the use of HTTPS and the potential differences in cookie handling.
