Thanks for replying to me. But I am not much aware about apache. I started it just before sometime ago. So please can you confirm it how can I do following:- Apache --- mod_jk connector ---tomcat Caching by mod_disk_cache and mod_cache Now if I changed any static file at tomcat(that is already cached at apache) must be re-cached in further request without shutting down apache and tomcat. Is it possible ? if so please can you give me guide me for configuration the same? Thanks a lot.. -----Original Message----- From: David Cassidy [mailto:david@xxxxxxxxxxxxx] Sent: Tuesday, February 26, 2008 7:20 PM To: users@xxxxxxxxxxxxxxxx Subject: Re: Server hanging with requests in "W" state Whats your timeout and keepalivetimeout settings set to ?
