I can tell a LOT of work went into this upgraded. I will be donating!
Have everything enabled and all features are working perfectly. (For the first time since we started using this about 6 months ago) It now seems fully compatible with IIS and wincache and this alone has made a big difference.
Under miscellaneous there and option that was check by default called "Verify rewrite rules".
Can/should this be unchecked after everything is working?
Thanks again for this brilliant update!!
