Enabling Tomcat to check for allowed referrer

For additional protection, you should enable Tomcat to check for allowed referrer.

Procedure

Edit the <TDC_HOME>/TalendDataCatalog/tomcat/conf/web.xml file.
Uncomment the two filter sections in the Checks referer is allowed section.
The variable ${server.fqdn} is substituted with the value of M_SERVER_FQDN in tomcat.properties.
Add as many init-param sections as needed to allow reference from other URLs.
Edit <TDC_HOME>/TalendDataCatalog/tomcat/conf/tomcat.properties by changing the M_SERVER_FQDN variable from localhost to <myMMServer.myDomain>.
