Not true -- $HTTP_SESSION_VARS is *not* like $_SESSION, and its values are *not*
auto-registered. In fact, I still have my copy of the 4.0.6 manual around, and it
specifically gives this as an example:
> Example 1. Registering a variable
>
> <?php
> session_register("count");
> $HTTP_SESSION_VARS["count"]++;

However, it's a little unclear on whether this should still work regardless of the
register_globals setting, as it also gives this as an example:
> Example 2. Registering a variable with register_globals enabled
>
> <?php
> session_register("count");
> $count++;

I guess I'd have to go away and try it to be sure of what behaviour occurs for each
setting of register_globals -- but there seems little point given that using $_SESSION
has been much the best option for several versions now!
Cheers!
