The field ID and value retrieved from the cache will be sent to the server for validation. To make sure they arrive at the destination successfully and unaltered, they are escaped using JavaScript's encodeURIComponent function. This enables safely transmitting any characters to the server, including characters such as "&" which otherwise would cause problems.
