How to secure the ASP.NET_SessionId cookie?

January 30, 2023 by Tarik

To add the ; secure suffix to the Set-Cookie http header I simply used the <httpCookies> element in the web.config:

<system.web>
  <httpCookies httpOnlyCookies="true" requireSSL="true" />
</system.web>

IMHO much more handy than writing code as in the article of Anubhav Goyal.
