To send data to the server from the client, you have some options:

• Send in a form.
• Use Ajax.
• Indirectly request a resource from the server and use a query string to send the information (for instance, adding an img element which uses a query string in its src). Not recommended, but possible and perhaps useful in some edge cases (for instance, when you need to send the data cross-origin and need to avoid the Same Origin Policy, as with many ad serving scripts).
• Have the data piggy-back on your next normal request by setting a cookie.

Given the scenario you describe, Ajax may be your best option.
