FWIW, the first two RewriteCond's g1smd provided must exist together (double conditions of both blank refer and blank UA), were they separate, the first line would end with an [OR]
They must exist together in the example g1smd gave, not the way I have it written. I have other conditions combined for brevity, keeping my entire .htaccess under 10k, including 100s of blocked ip ranges. I also got rid of the heavy defensive scripts to improve response time.
