  1. POWhy Can WebMethod Access Session State Without EnableSessionState?
    text
    copied!<p>I have a method on a page marked as a <code>[WebMethod]</code> that uses some session state as part of its operation. After I wrote this code, I suddenly had a flash of memory that you need to use <code>EnableSessionState</code> when you use session state in a <code>[WebMethod]</code> (e.g. see here: <a href="http://msdn.microsoft.com/en-us/library/byxd99hx.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/byxd99hx.aspx</a>). But it seems to be working fine. Why?</p> <p>Sample code behind:</p> <pre><code>protected void Page_Load(object sender, EventArgs args) { this.Session["variable"] = "hey there"; } [System.Web.Services.WebMethod] public static string GetSessionVariable() { return (string)HttpContext.Current.Session["variable"]; } </code></pre> <p>Sample body html:</p> <pre><code>&lt;script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; function getSession() { $.ajax({ type: 'POST', url: 'Default.aspx/GetSessionVariable', data: '{ }', contentType: 'application/json; charset=utf-8', dataType: 'json', success: function (msg) { document.getElementById("showSessionVariable").innerHTML = msg.d; } }); return false; } &lt;/script&gt; &lt;form id="form1" runat="server"&gt; &lt;div id="showSessionVariable"&gt;&lt;/div&gt; &lt;button onclick='return getSession()'&gt;Get Session Variable&lt;/button&gt; &lt;/form&gt; </code></pre>
