Deprecated. This option will be removed in Tomcat 7 onwards where the default of true will always be used.
If the value of this flag is false, all case sensitivity checks will be disabled. If not specified, the default value of the flag is true.
NOTE: This flag MUST NOT be set to false on the Windows platform (or any other OS which does not have a case sensitive filesystem), as it will disable case sensitivity checks, allowing JSP source code disclosure, among other security problems.
