It seems that it's possible to soft-crash the application pool serving a website by requesting a URL to a PHP file followed by /somefile.ext. Reproduce code: --------------- Access any existing php file using url http://www.domain.com/file.php/test.htm Expected result: ---------------- PHP should return "No input file specified." Actual result: -------------- Application pool crashes and recycles. If rapid fail protection is enabled and the url is accessed several times consecutively, the application pool will shutdown after reaching the maximum amount of errors.
