How it was found

Since you are running on a secure connection, https, you should be ensuring that everything runs securely on your client's / visitors case. I have check the cookie session of IRCCloud and found out that it is not flag as secure.

Whenever a cookie contains sensitive information or is a session token, then it should always be passed using an encrypted tunnel. For example, after logging into an application and a session token is set using a cookie, then verify it is tagged using the ";secure" flag. If it is not, then the browser believes it safe to pass via an unencrypted channel such as using HTTP.
