Relative Images in Redirected Pages
I've just discovered a bug/issue when using redirected pages. Let's assume I have the following in a page (Animal.aspx)   <asp:Image id="i1" runat="server" ImageUrl="~/Images/foo.jpg" />
In web.config I have:   <urlMappings enabled="true">     <add url="~/Animals/Dog.aspx"        mappedUrl="~/Animal.aspx?Animal=Dog" />   </urlMappings> Run the page and the image doesn't show, because the ImageURL is incorrectly rebased.

The solution is to do the rebasing yourself; there's a whole thread on about ASP.NET Paths on Rick Strahl's Blog; there's a nice FixupUrl() method in the comments. Alternatively you can use the VirtualPathUtility: i1.ImageUrl = VirtualPathUtility.ToAbsolute("~/Images/foo.jpg");
