Pure Redirection using WebRequest and WebResponse

RIn ASP.NET C# general method which is used to redirect from one page to another is Response.Redirect("url").

But a smart user can also navigate to a page by simply entering URL in address bar.

 

There may be some cases where you are not suppose to allow user to hit a page by directly entering URL.

In such cases a feasible  way to implementation is use WebRequest and WebResponse

 

Below is simple code for above scenario.

 

 Button event on click of which you want to jump to URL:

protected void btnRedirect_Click(object sender, EventArgs e)
{
      WebRequest req = null;
      WebResponse rsp = null;
      string  xmlString = @"<request>Some data</request>";
      //It is not mandatory to pass any request parameter.

      req = WebRequest.Create("URL"); //URL of desired page can be entered here
      req.Method = "POST"; //OR GET
      req.ContentType = "text/xml"; //OR json

      StreamWriter writer = new StreamWriter(req.GetRequestStream());
      writer.WriteLine(xmlString);
      writer.Close();

      rsp = req.GetResponse();

}

 Page load event on which the request is to be handled: 

protected void Page_Load(object sender, EventArgs e)
{
      Page.Response.ContentType = "text/xml";
      StreamReader reader = new StreamReader(Page.Request.InputStream);
      string  xmlRequestString = reader.ReadToEnd();
      XDocument doc = new XDocument.Parse(xmlRequestString);
      string reqData = doc.Root.Element("request").Value;
      //
      //Handle the conditions you want to handle here.
      //
}

In this way, the desired results can be achieved.
