ASP.NET Handler (.ashx) with long Query String Parameters

Question

I want to know what is the best solution for creating ASP.NET HTTP Handler (.ashx) with long Query string parameters, as i have parameter like "description" which will be a long string which will make a problem in URL when access it by HTTP Request.

Answer 1

if you just want use GET method,you can't solved this problem,you can set it at What is the maximum length of a URL? why.

you can change you .ASHX file accept the POST method.

<httpHandler>
  <add path="1.ashx" verb="post" type="" />
</httpHandler>

your server-side code like this :

public void ProcessRequest(HttpContext context)
    {
        var stream = context.Request.InputStream;
        using (StreamReader sr = new StreamReader(stream))
        {
            var text = sr.ReadToEnd();
        }
    }

or alternative(based on your client-side how to send data)

   public void ProcessRequest(HttpContext context)
    {
       var text= context.Request.Form["text"];
    }

your client-side:

 <script type="text/javascript">
     $.ajax({
        type: 'POST',
        url: "1.ashx",
        data: { name: "John", time: "2pm" }
    });
</script>
