We are attempting to access a website with a .org extension and only get the "This page cannot be found - http 400 bad request" The users are behind a Sonicwall Pro 3060 firewall. Outside this firewall there is no problem getting this website to open properly. There is no content filtering or blacklisting active on the firewall. The website is also available with a .com extension and there is no problem opening the site behind this firewall. What would cause this situation?
