if (e.CommandName == RadGrid.ExpandCollapseCommandName && !e.Item.Expanded)I have two web front end servers configured with Load Balancer and one application server outside the load balancer configuration , and although I configured the machine key on both servers in the web config with the same values as you see in the below:
<machineKey validationKey="AEDAB4B755EB987CBBB4C56EA861BD8A6D2DF4425A9FB7F8" decryptionKey="96A44D2D02FEBBEF8E1FC94DBE4820AC67AEB8BA95DB9C53" validation="SHA1" />
WebResources references are different as you see in the below:
Web front end 1
<link href="/WebResource.axd?d=EUJeeKSuEHqtpWqYXKVDjXJwZS7qQrsjgWJPMkRyIcYidNaMCqJlrJfAZm184B8RJVb1d3QvRziOvCOXxIbf3b-svaG69jUCbEVxwomMUDQ_oerenUHELlXDkKGilSlk0&t=634183493748290221" type="text/css" rel="stylesheet" class="Telerik_stylesheet" />
Web front end 2
<link href="/WebResource.axd?d=TFV8V9QizTHQudTQT7Dl7QlzBUw0G7zm7h08wDFQ_UzipCD3e-UfPbUM_K99qXB2tXDFm-IsNhtDmJRjcry3StO61iot2FcGK7_7XrsDCngKWEvSyBafv6D598hVEKY0LXNXFO8k-WFPbcklJ7FhAo0nSvrBXMyffRQN283jgYoatDQV0&t=634509229928059050" type="text/css" rel="stylesheet" class="Telerik_stylesheet" />
Application server
<link href="/WebResource.axd?d=EUJeeKSuEHqtpWqYXKVDjXJwZS7qQrsjgWJPMkRyIcYidNaMCqJlrJfAZm184B8RJVb1d3QvRziOvCOXxIbf3b-svaG69jUCbEVxwomMUDQ_oerenUHELlXDkKGilSlk0&t=634183493748290221" type="text/css" rel="stylesheet" class="Telerik_stylesheet" />
So I need to know why in the web front end 2 the web resources url refrences is different because it produce errors when redirect from one server to the other.
