title: Using a query string in an excel hyperlink to an ASP.Net Web Application
body: <p>I want to pass some data between an existing excel application and an existing ASP.Net VB Webforms application.</p>
  
  <p>I thought a hyperlink with some query string variables would be the most straightforward means of doing this. However, it seems that the hyperlink does not retain the session of the logged in user.</p>
  
  <p>Testing this with the same URL on a webpage does work. So it seems Excel is starting a new session. Any ideas on how to make Excel hyperlinks behave the same way a browser hyperlink does?</p>
