moved here to continue the problem
I have persistance over the VS so I think that might be the problem cause even after I used detach and rr it still select the same node .
I have searched the forum for a way to disable the persistance but it all show how to create persistance .
so how can I overcome the persistance problem

- The_BhattmanWhere did you apply the persistance?

The original post was in the config forum (Click here). You should be able to use 'persist none' to disable persistence. If the application requires persistence, you'd want to re-enable it in a subsequent event using the persist command (Click here) again.
Aaron- hoolioThat looks okay. Can you try that as you have it?
If it still doesn't work and the same node is still specified, could you try setting a variable in HTTP_RESPONSE_DATA to 0 initially and to 1 if you're using HTTP::retry? Then check to see if that variable is set in HTTP_REQUEST. If it's set to 1, use the persist command to specify the persistence profile type and options.

}
}
not working as it still selecting the same node over and over agian
and once it reached to the max no of retires = no of nodes in pool it stop and direct the user to the error page
why i have used the persist none so it should work
