HTTP Headers

This is a quick and a small post on reading the HTTP headers in ASP.NET. Code gets the HTTP header key – value pairs and write it to a text file.

   1: protected void Page_Load(object sender, EventArgs e)

   2: {

   3:     var headers = Request.Headers;

   4:     StreamWriter writer = new StreamWriter(Server.MapPath("~/data.txt"));

   5:  

   6:     foreach (var item in headers.AllKeys)

   7:     {

   8:         string data = item + "---" + headers[item];              

   9:         writer.WriteLine(data);

  10:     }

  11:  

  12:     writer.Flush();

  13:     writer.Close();

  14: }

Output text file as follows.

   1: Connection---Keep-Alive

   2: Accept---text/html, application/xhtml+xml, */*

   3: Accept-Encoding---gzip, deflate

   4: Accept-Language---en-US

   5: Host---localhost:24859

   6: User-Agent---Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)
