how to pass session parameter from jquery to ASHX handler

Question

Below is my Jquery code and I would like to pass Session paramater e.g. Session["ID"]. Jquery calls ASHX page

All below parameters are working fine and the session parameter has a value, but how can I pass session paramater from Jquery?

So below code "paramater Sessionparameter" should be replaced with Session["ID"] or something like that. How can I do that?

please advice?

   $('input[name$=btnTab1Save]').click(
             function (e) {
                 // debugger;
                 // AJAX call to the handler
                 $.post(
                    'Consulting.ashx',
                 // data to the handler in the form of QueryString
                    {
                    tab: 'tab1',
                    // id is the second column within the row
                    Ilac_id: prevRow.find('td:eq(0)').text(),
                    ID: SESSION_PARAMATER,
                    begindate: $('input[name$=begindate]').val(),
                    weigth: $('input[name$=weigth]').val(),
                    continue: true,
                    freq: $('input[name$=freq]').val(),
                    reason: $('input[name*=radListreason]:checked').val(),
                    freq2: $('input[name$=radListfreq2]:checked').val(),
                    freetext: $('input[name$=freetext]').val()
                },
                 // callback function
                 // data is the JSON object
                    function (data) {
                        if (data.Success) {
                            // close the tab
                        }
                    },
                    "json"
                );
             });

I can read my parameters like Convert.Toint(context.Request.Form["ID"]));

 data.weigth = Convert.ToInt32(context.Request.Form["weigth"]);

I tried : '<%= Session["ID"] .ToString() %>', but it's not working....

If the information is in the session, the ASHX can access directly the session content.

You need to implement IReadOnlySessionState and you will be fine.

<% @ webhandler language="C#" class="MyClass" %>

using System;
using System.Web;
using System.Web.SessionState;

public class MyClass: IHttpHandler, IReadOnlySessionState
{
   public bool IsReusable { get { return true; } }

   public void ProcessRequest(HttpContext ctx)
   {
       ctx.Response.Write(ctx.Session["ID"]);
   }
}
