An ASP.NET application sends letters in HTML format with links to external images. These images are placed in the same folder where the application is deployed. So before sending it modifies a letter template in such way what the links are correct.
Now I use
new UriBuilder(Request.Url.Scheme, Request.Url.Host,
Request.Url.Port, ResolveUrl("~")).ToString()
to get a path from where the application is run, but I want something more simple.
Some answers to this related question were useful, but I still hope for better solution.
Thank you!
