Making relative urls in asp.net webform custom classes without Request

I have some kind of a job scheduling implemented which calls a function ProcessJob. Now inside this method I need to generate url to one of my pages i.e DoanloadPage.aspx?some_params. That url is sent to user via email and when user clicks that link, it will take to the page.

The problem here is that I am not generating url in a web request method or I don't have access to the Request object. URL need to be generated in a custom class which is threaded i.e not in a web request.

So I can't go with these solutions:

HostingEnvironment.MapPath("test.aspx");
VirtualPathUtility.ToAbsolute("123.aspx");
HttpContext.Current.Request.Url.Authority;


None of these works because I think they all rely on current request or session somehow. So how do I generate urls for my app inside my code so I can use them anyway I want.

The question is widely applicable to a large audience. A detailed canonical answer is required to address all the concerns.
