title: How can I share a session across multiple subdomains in ASP.NET?
body: <p>I have an application where, in the course of using the application, a user might click from</p>
  
  <pre><code>virginia.usa.com
  </code></pre>
  
  <p>to</p>
  
  <pre><code>newyork.usa.com
  </code></pre>
  
  <p>Since I'd rather not create a new session each time a user crosses from one subdomain to another, what's a good way to share session info across multiple subdomains?</p>
