Ah, so this was possible, and occasionally done back then, but the real reason it wasn&#x27;t was less to do with capability, and more to do with everyone wanting to ride on top of Apache.  Apache handled a lot of stuff you wouldn&#x27;t want to in a CGI (at that time), so it made sense to use it.  Apache forked (and&#x2F;or threaded depending on era), so variables shared in memory wasn&#x27;t common.  That said, people set up shared memory regions, or used file based sessions and &#x2F;dev&#x2F;shm, which is functionally the same, and had much the same thing.
