This movie uses PHP to verify that the IP address of the visitor is the same IP address used to access the holding page. If there is no known IP address used to access the holding page, then it is assumed that the movie has been illegally linked.
A session variable is used to hold the authorised IP address, and a querystring variable is used to send the session id, in case the user has cookies disabled. This ensures that the technique will work for 100% of legitimate users.
Note that because of the querystring, the technique should only be used with a tiny loader movie, which should load the main movie itself. This is because the querystring will prevent the movie being cached locally, and page refreshes may take disproportionately long to load if the entire movie is reloaded every time. Provided that the loader is small, and only that part is reloaded each time, the extra delay should not be noticeable.
Authorised session ID: f399c23eb05a3101893791fc8b0d37c6
Authorised IP address: 38.103.63.59
