Security warning

Enabling this setting can be potential security risk - taken from Tomcat decumentation:
The org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH and org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH system properties allow non-standard parsing of the request URI. Using these options when behind a reverse proxy may enable an attacker to bypass any security constraints enforced by the proxy.
