This is conditional on whether a client computer accepts cookies. If the client does not accept cookies, the function automatically appends all required client identification information to a URL. If the client accepts cookies, it does not append the information.
This function automatically determines which identifiers are required and sends only the required information. It provides a more secure and robust method for supporting client identification than manually encoding the information in each URL. This is because it sends only required information when it is required, and it is easier to code.
