Jason, I have general understanding of what you are recommending. However, I need clarification on a couple of things:
1) When you stated to upload all pages, are you referring to all the pages that eCart created through the Checkout Wizard, such as, checkout, confirm pages, all error and success pages, etc.?
2) With respect to the htaccess rule...am I to copy and paste the code (given at the link provided) at the top of each eCart page? If not, how is the code to be applied?
