Add Cookies to HTML Page Request

EVO HTML to PDF Converter allows you to add HTTP cookies when you request the HTML page. The HTTP cookies to be used when the HTML page to convert is requested can be added to HtmlToPdfConverterHttpRequestCookies collection.

A valid cookie name and a RFC 6265-encoded value must be provided.
