Regardless of whether cookies are used or not, Client variables work the
same way.
1. Browser visits page for first time.
2. CF sees that the browser doesn't send CFID and CFTOKEN (whether by cookie
or URL variable).
3. If set to do so, which is the default setting, CF issues CFID and CFTOKEN
cookies. It also stores the values for CFID and CFTOKEN itself, and
associates those values with a set of variables. These variables may be
stored in the server's registry, or in a database, or in one big cookie sent
back to the client.
4. On subsequent page requests, if the browser returns the CFID and CFTOKEN
values, the server knows to associate that request with the right set of
variables. If not, the server will again attempt to issue CFID and CFTOKEN
cookies.
Now, if you don't want to rely on the browser's use of cookies, you can set
CFID and CFTOKEN values within your code, so that any hyperlinks within your
pages, or form action attributes, or JavaScript location changes, pass those
CFID and CFTOKEN values back to the server within the URL. As you can
imagine, this is significantly more work than simply relying on cookies, but
it can be used as an alternative.
