Hey Raja Valavan

 

To give you an example, I had an FTP server being load-balanced on my LTM. During the FTP transfer I removed the FTP pool member. This did not affect my download and even when my download finished, I could initiate new downloads without any issues (when the pool member was deleted from the pool).

 

So in my environment it works fine.

 

But why don't you just use Forced Offline or Disabled? In that case you can be certain that active connections will be unaffected. The difference between the two is:

 

Disabled - Will allow active and persistent connections

 

Forced Offline - Will only allow active connections.
