Severity: 3-Major


When HTTP response is served from cache, a transfer stalls due to incorrect value in Content-Length header.


Transfer stalls as the client is expecting more bytes from peer (due to Content-Length header being advertised as greater than than object's actual size).


- Virtual server with HTTP profile that has standard chunking settings. - Web acceleration profile is configured on the virtual server. - HTTP response is served from AAM cache.


For the HTTP profile used, set request-chunking to selective.
