Problem Description: ColdFusion 2016,0,12,315717 Windows Server 2016 IIS 10 My IIS root directory contains an index.cfm, which is displayed when I navigate to http://localhost because index.cfm is set to be the IIS default page. After installing the recent Update 12 on ColdFusion 2016 AND recreating the connector, accessing the root URL occasionally returns a 404 not found error, instead of serving the index.cfm file that exists. Note that this does not happen all the time, but is intermittent. For example, I could reload http://localhost 10 times, and perhaps 3 of those requests will return a 404, while the other requests will properly display the index.cfm. Navigating to http://localhost/index.cfm (with the filename) always works, and never returns a 404 error. Each time the incorrect 404 is returned, the isapi_redirect.log contains the following entry: [warn] jk_check_for_path_attack::jk_util.c (2457): Path attack using [/] This issue is similar to the admin page 404 issue in CF-4205252 (I'm opening this new issue because I'm not seeing this issue on the admin page) as well as the 404 issue discussed in the comments of https://coldfusion.adobe.com/2019/09/coldfusion-2018-release-update-5-coldfusion-2016-release-update-12 Steps to Reproduce: -Install Update 12 on ColdFusion 2016 running on IIS 10 -Rebuild connector -Repeatedly hit the server root URL and observe returned HTTP status codes Actual Result: Many requests fail with status code 404. Expected Result: All requests return the index.cfm contents with status code 200. Any Workarounds: None found.
