SYMPTOMS
When you run Microsoft Application Center 2000 Service Pack 2 (SP2) in a cluster environment, you experience one or both of the following symptoms:
 * The Request Forwarder may cause the Inetinfo.exe process to run at 100 percent CPU utilization.
 * If you have configured Microsoft Internet Information Services (IIS) to use HTTP Compression, a request that is forwarded by the Request Forwarder may be blank in Microsoft Internet Explorer on a client computer.



CAUSE
This problem occurs because the Request Forwarder does not correctly process the chunked HTTP responses.
