Disabling the Caching of Host Name Resolutions

To specify that host name resolutions are never cached:

  1. On the Instance Administration page, stop the application server of the instance that you want to modify.
  2. Open the java.security file with a text editor. The default path for this file is C:\Program Files (x86)\Silk\Silk Central 20.0\instance_<instance number>_<instance name>\lib\jre\lib\security on the application server. If your application server runs in 64-bit mode, use the jre64\lib\security folder instead.
  3. Locate the line #networkaddress.cache.ttl=-1 and change it to networkaddress.cache.ttl=0.
    Note: The "#" character needs to be removed to uncomment this line.
    This change should be discussed with your network administrator, as there may be security concerns in doing this.
  4. Save and close the file.
  5. Restart the application server.
