On our main site we are redirecting all http traffic to https using a URL rewrite rule. On our test and dev site we are not applying this redirect. I have set up IIS 7 to allow for custom extensions as seen here: http://devnet.kentico.com/docs/devguide/index.html?configuration_of_custom_url_extensions.htm and set up the individual page to use the appropriate custom extension as seen here: http://devnet.kentico.com/docs/devguide/index.html?configuration_of_custom_url_extensions.htm. This has been done for all sites and servers. The custom extensions are working on test and dev sites as seen in the screenshots, however the same custom extensions are not working on the live site that has the redirect rule. Screenshots are attached of this as well. I cannot figure out why this would be happening. Ignore the fact that on dev it is dev.66fcu.org and the live is truitycu.org (we rebranded in the middle of development and launching and I just haven't gotten a chance to adjust dev). Any ideas?
