==== Variables ====

With some scripting languages such as Lua it was observed that is better to store the value of a Kamailio pseudo-variables inside a local variable if used many times. For example:

<code lua>
	if KSR.corex.has_user_agent() then
		local K_ua = KSR.pv.gete("$ua");
		if string.find(K_ua, "friendly-scanner")
				or string.find(K_ua, "sipcli") then
			KSR.sl.sl_send_reply(200, "OK");
			KSR.x.exit();
		end
	end
