If I have managed to locate and verify the existence of a file using Server.MapPath and I now want to send the user directly to that file, what is the fastest way to convert that absolute path back into a relative web path?

The absolutePath function works by beginning at the starting folder and moving up one level for each "../" in the relative path. Then it concatenates the changed starting folder with the relative path to produce the equivalent absolute path.
In simple words, an absolute path refers to the same location in a file system relative to the root directory, whereas a relative path points to a specific location in a file system relative to the current directory you are working on.
Relative links show the path to the file or refer to the file itself. A relative URL is useful within a site to transfer a user from point to point within the same domain. Absolute links are good when you want to send the user to a page that is outside of your server.
Perhaps this might work:
String RelativePath = AbsolutePath.Replace(Request.ServerVariables["APPL_PHYSICAL_PATH"], String.Empty); I'm using c# but could be adapted to vb.
