URL to PFD using itext Sharp

Hi there,
I have application where i need to convert whole page from html to pdf. i found that there is third party dll i.e itext sharp is used to convert it from HTML to PDF.
I want to convert actual url (whole page) to pdf.

Is this possible ? if yes then how ? If no then what is the solution ?
Please help....
