In this article I would like to take you through deploying an HTTP module in SharePoint 2013.

Scenario

Redirect users from accessing the Site Contents page (viewlsts.aspx).

Procedure

Open Visual Studio and create a Class Library project.

Add a reference to the System.Web library.

System web

Replace the class file with the following code where:

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5. using System.Threading.Tasks;
  6. using System.Web;
  7. using System.Web.UI;
  8. namespace SPModule
  9. {
  10. public class SPModule : IHttpModule
  11. {
  12. public void Dispose() { }
  13. public void Init(HttpApplication context) { context.PreRequestHandlerExecute += context_PreRequestHandlerExecute; }
  14. void context_PreRequestHandlerExecute(object sender, EventArgs e)
  15. {
  16. HttpApplication app = sender as HttpApplication;
  17. if (app != null)
  18. {
  19. Page page = app.Context.CurrentHandler as Page;
  20. if (page != null) { if (HttpContext.Current.Request.Url.AbsoluteUri.Contains("_layouts/15/viewlsts.aspx")) { HttpContext.Current.Response.Redirect("http://www.bing.com"); } }
  21. }
  22. }
  23. }
  24. }
Build the code and copy the DLL to the IIS SharePoint BIN folder as shown below.

SP Module

Now, open the web.config and find the modules section. (Please note that there is another httpModules section that is not for our purpose.)

html code

Add your class name in the format Assembly.ClassName. Save the changes.

Refresh your SharePoint site and try accessing the viewlsts.aspx page using the URL given below:

http://server/_layouts/15/viewlsts.aspx

You should see the page is redirected to www.bing.com.
