To specify that host name resolutions are never cached:
Stop the application server.
Open the
java.security file with a text editor.
The default path for this file is
C:\Program Files (x86)\Silk\Silk Performance Manager <version>\lib\jre\lib\security on the application server.
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.
