Forms Authentication Ignoring Default Document

This was my solution:

In Global.asax, method: Application_BeginRequest, place the following:

if (Request.AppRelativeCurrentExecutionFilePath == "~/")     HttpContext.Current.RewritePath("HomePage.aspx");

Nice and simple, and you have a chance to build logic around what home page you want to use if your website uses multiple home pages based on configuration variables.

I was seeing this same problem when attempting to hit the root path and I tried everything previously mentioned. It seems Asp.net 4.0 adds two ExtensionlessUrl modules to applicationhost.config for IIS 7. You can remove these modules by adding the following to your web.config

<system.webServer>  <handlers>    <remove name="ExtensionlessUrl-Integrated-4.0"/>    <remove name=" ExtensionlessUrl-ISAPI-4.0_32bit "/>  </handlers></system.webServer>

How extensionless urls are handled by asp net v4

What I ended up doing to fix this is writing a few lines of code in my login page to check for a Request.QueryString["ReturnUrl"] of "/". If it found that, then it redirected to default.aspx.

I couldn't find ANY way to make forms authentication not intercept calls without a page specified (e.g. www.mysite.com). :( I even tried .NET 4 URL Routing and that didn't prevent Forms Authentication from hijacking the request either.

Below is the code I used in login.aspx:

protected void Page_Load(object sender, EventArgs e){    if (!(IsPostBack || IsAsync))    {        string returnUrl = Request.QueryString["ReturnUrl"];        if (returnUrl != null)            if (returnUrl == "/")                Response.Redirect("default.aspx");    }}
