EVO HTML to PDF Converter allows you to add HTTP headers when you request the HTML page. There are various standard HTTP headers offering important information to web server about the capabilities of the browser like the accepted content type, accepted encoding, accepted language, connection mode, user agent.
The HTTP headers to be used when the HTML page to convert is requested can be added to HtmlToPdfConverterHttpRequestHeaders collection.
