title: how do I return to the same exact page after posting a form?
body: <p>I'm posting data to a page called process.aspx that handles some business logic with the following code: </p>
  
  <pre><code>&lt;%@ Page Language="C#" %&gt;
  &lt;%
      MyData.process(Request);
      Response.Redirect("")
  %&gt;
  </code></pre>
  
  <p>this page I will be calling from a variety of pages. Is there some way of knowing from which page my form was submitted? I was thinking something along the lines of writing:</p>
  
  <pre><code> &lt;form id="frmSystem" method="post" action="process.aspx?page=&lt;%=  %&gt;"&gt;
  </code></pre>
  
  <p>However I don't know what to write in between the <code>&lt;%=  %&gt;</code> to get the current page name. Can anyone help please?</p>
