UpdatePanel on web farm with 3 servers

Question

Im getting an error:

Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_plhBody_ctrMyPanel_updPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.

if one request is sent to server 1 and then after clickin for example a button request is sent to server 2.

How can I get rid of that ?

thanks for any suggestions

您需要使用Persistence进行负载平衡器设置，以便来自一个用户的请求将保留在同一服务器上。
