There are good reasons to use global variables, but can also be troublesome if you're not careful. Also, while you can technically create a global variable anywhere, if you create one outside of RULE_INIT, or try to write to one later, you'll disable CMP.
All variables, other than global ones, are "connection-scoped", meaning that they exist within the span of a single TCP connection. Because of this, you're best bet is usually to create them at the absolutely lowest layer (the CLIENT_ACCEPTED event) where they're guaranteed to exist everywhere else.
