Java – Trailing slash is not inserted in Spring Boot application

It's an old post, but as of Tomcat 7.0.67, you need to add the following attribute to your context.xml file:

<Context mapperContextRootRedirectEnabled="true">...</Context>

As per the 7.0.67 changelog:

Move the functionality that provides redirects for context roots and directories where a trailing / is added from the Mapper to the DefaultServlet. This enables such requests to be processed by any configured Valves and Filters before the redirect is made. This behaviour is configurable via the mapperContextRootRedirectEnabled and mapperDirectoryRedirectEnabled attributes of the Context which may be used to restore the previous behaviour.

And in the Tomcat context documentation:

mapperContextRootRedirectEnabled: If enabled, requests for a web application context root will be redirected (adding a trailing slash) if necessary by the Mapper rather than the default Servlet. This is more efficient but has the side effect of confirming that the context path exists. If not specified, the default value of false is used.

With ASP.Net 1.1, first you have to set the runat attribute on the title markup :

<title id="PageTitle" runat="server">WebForm1</title>

Then from the code behind :

C#

// We need this name space to use HtmlGenericControl
using System.Web.UI.HtmlControls;

namespace TestWebApp
{

      public class WebForm1 : System.Web.UI.Page
      {
            // Variable declaration and instantiation
            protected HtmlGenericControl PageTitle = new HtmlGenericControl();

            private void Page_Load(object sender, System.EventArgs e)
            {
                  // Set new page title
                  PageTitle.InnerText = "New Page Title";
            }
      }
}

VB

Imports System.Web.UI.HtmlControls

Namespace TestWebApp

    Public Class WebForm1
        Inherits System.Web.UI.Page

        Protected PageTitle As HtmlGenericControl = New HtmlGenericControl()

        Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

            PageTitle.InnerText = "New Page Title"
        End Sub

...

    End Class
End Namespace
