loading data into session only once
<p>I have a master page where I'm loading some data into the session.</p>

<p>I put the lines of code that call my queries in the <strong>Page_Init event of the master page</strong>, inside an if statement</p>

<p><code>if (!Page.IsPostBack){ load data from queries into the session</code> } </p>

<p>Is this what I need for all the session data to be loaded only once per session. What about call backs? Do I also need to check to avoid a reload of session data on call backs? Any other condition I need to check to avoid unnecessary reloads of session data? I'm looking to run the queries inside the condition statement only once.</p>

<p>Thanks.</p>
