URL rewriting breaks ASP.NET 2's themes
If you try to use
URL rewriting
and ASP.NET 2 themes at the same time, you will likely get
broken pages, because the two don't mix very well.
A
typical link to a theme's stylesheet looks like this in the
generated HTML:
<link href="App_Themes/Theme1/StyleSheet.css"
type="text/css" rel="stylesheet" />
The problem is that these links to CSS documents are
using relative paths, which is not going to work fine if you
use
RewritePath
on your web requests.
Update: as Scott and Wilco
wrote in comments, a much simpler solution is to use the new overload of the RewritePath method
that takes one additional parameter named
"rebaseClientPath".
Thomas Bandt has a solution, described in German (the source is available), that
relies on response filters.
Here is another solution I
use. It consists on overriding the
Render
method in a base page or in a master page:
protected override void Render(HtmlTextWriter writer)
{
foreach (Control control in Page.Header.Controls)
{
HtmlLink link;
link = control
as HtmlLink;
if ((link != null) &&
link.Href.StartsWith("~/"))
{
if
(Request.ApplicationPath == "/")
link.Href =
link.Href.Substring(1);
else
link.Href =
Request.ApplicationPath+"/"+link.Href.Substring("~/".Length);
}
}
base.Render(writer);
}
