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.
    CAUTION:
    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.
