One gotcha that people sometime run into when using Url
Rewriting for the very first time is that they find that their image and CSS
stylesheet references sometimes seem to stop working. This is because
they have relative references to these files within their HTML pages - and when
you start to re-write URLs within an application you need to be aware that the
browser will often be requesting files in different logical hierarchy levels
than what is really stored on the server.
For example, if our /products.aspx page above had a relative
reference to "logo.jpg" in the .aspx page, but was requested via the
/products/books.aspx url, then the browser will send a request for
/products/logo.jpg instead of /logo.jpg when it renders the page. To
reference this file correctly, make sure you root qualify CSS and Image
references ("/style.css" instead of "style.css"). For
ASP.NET controls, you can also use the ~ syntax to reference files from the
root of the application (for example: <asp:image
imageurl="~/images/logo.jpg" runat="server"/>
Hope this helps,
