ASP.NET MVC 3 - Custom SEO friendly routes - asp.net-mvc-2

Question

I've defined the following route:
routes.MapRoute(
null,
"foo/{id}/{title}",
new { controller = "Boo", action = "Details" }
);
When I call this method:
Url.Action("Details", "Boo", new { id = article.Id, title = article.Title })
I get the following URL:
http://localhost:57553/foo/1/Some%20text%20Š
I would like to create a new route that will lowercase all characters and replace some of them.
e.g.
http://localhost:57553/foo/1/some-text-s
Rules:
Uppercase -> lowercase
' ' -> '-'
'Š' -> 's'
etc.
Any help would be greatly appreciated!

Answer 1

Seems like a perfect candidate for a custom route:
public class MyRoute : Route
{
public MyRoute(string url, object defaultValues)
: base(url, new RouteValueDictionary(defaultValues), new MvcRouteHandler())
{
}
public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
{
values = new RouteValueDictionary(values);
var title = values["title"] as string;
if (!string.IsNullOrEmpty(title))
{
values["title"] = SEOify(title);
}
return base.GetVirtualPath(requestContext, values);
}
private string SEOify(string title)
{
throw new NotImplementedException();
}
}
which will be registered like this:
routes.Add(
"myRoute",
new MyRoute(
"foo/{id}/{title}",
new { controller = "Boo", action = "Details" }
)
);
Now all you have to do is to implement your SEO requirements in the SEOify function that I left. By the way you could get some inspiration from the way StackOverflow does it for the question titles.
