When trying to browse a .CFC file directly you will get the following error:
Error Occurred While Processing Request
Could not import the tag library specified by "../administrator/cftags/".
following error was encountered:
Please ensure that you have specified a valid tag library.
is because on a normal installation of ColdFusion, accessing a .CFC
file directly will get you to a ColdFusion login screen. We have
disabled this for security reasons so you just get this error with a
non-existent path instead. If you're just trying to test your CFC
you'll need to call it from your ColdFusion code.
