HTTP Cache Issue

Question

Hi, &nbsp;
I am load balancing for 5 servers. If one of the server is going down due to some issue, users are still hitting on this server, though the F5 LB showing this node is down. &nbsp;
Until or unless we will clear the user IE cache browser they will not able to use the new server. I dont have special configuration for the http://test.abc.com. Simple HTTP load balancing. &nbsp;
How can i redirect the user to the health server without doing anything at the IE level. My numbers of users are more and i cannot go and clear the cache to user by user. &nbsp;
How can i fine tune the F5 LB that user automatically redirect to health server in case of exisiting serer is down without take any action at the user level.&nbsp;

What setting have you got configured for Action on Service down? If I recall it's a Pool setting.&nbsp;
See https://devcentral.f5.com/articles/ltm-action-on-service-down&nbsp;
Hope this helps,&nbsp;

I have setting on the pool &nbsp;
Action On Service Down ===== None&nbsp;

So existing and persistent connections will attempt to use the downed pool member. Try changing to reselect.
