Hi this must be a good thing i think it has to do with base 64 encoding protection but im not really sure what it does. this is in one of my subdomains, i added it awhile back from a converstion with my old host tech support but again i would like to put some doc in the htaccess file as to what it does so i can remember lol..

follow symlinks is about this, and i read about that, that is a good thing so i will leave that.
