DenyIfRequestHeader
Learn how to use the DenyIfRequestHeader config.txt directive to specify browse headers to indicate that access should be denied to EZproxy.
DenyIfRequestHeader specifies browser headers that, if present in EZproxy requests, indicate that access should be denied to EZproxy. It is extremely unusual to deny access to EZproxy based on a header sent by a browser, but if this action is required this directive should be used.
DenyIfRequestHeader is a repeatable, position-dependent config.txt directive. Optional filename is a user visible document of this directive.
