问题
I have a MVC4/.Net 4 website running on IIS 7.5. In my web.config file I have the following in my block:
<urlMappings enabled="true">
<add url="~/2013calendar" mappedUrl="~/CustomerService/RequestPocketCalendar" />
<add url="~/teachers" mappedUrl="http://www.somexternalsite.com/teachers/" />
</urlMappings>
The local redirects all work great, but anything that is redirecting off the site, such as the /teachers link in the above example return "http://www.somexternalsite.com/teachers" is not a valid virtual path.
What am I missing here?
回答1:
If I'm not mistaken, the mappedUrl field is a path relative to the root of the application. As such, "http://www.somexternalsite.com/teachers/" is not valid.
If you'd like to configure this to redirect, I would just create a "Teachers" action in your root controller, then use the following:
return Redirect("http://www.somexternalsite.com/teachers");

Well I ended up creating a page to handle external redirects such as follows:
redirect.aspx
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
void Page_Load(object sender, EventArgs e)
{
var page = Request.QueryString["page"];
Response.Redirect("http://"+page);
}
</script>
So in my web.config I have external files referenced as such:
<add url="~/teachers" mappedUrl="~/redirect.aspx?page=www.somexternalsite.com/teachers/" />
Works great!
