When enabling the webcache in Portal:
-> Administer TAB
-> Global settings
-> cache TAB
WWC-40018 error with HTTP-404 is raised.
A TCP sniffer placed on the webcache invalidation port doesn't show any packet coming. In Portal 10.1.4.0.0 it might show a result as being reported as a possible DNS error as apposed to a 404 error.
All invalidations examples found in middle tier $ORACLE_HOME/webcache/examples are working fine.
When clearing the webcache in Portal ->builder-> administer TAB -> Global settings -> cache TAB WWC-40019 is raised.
