Hi Henrik, Wouldn't reducing the connect_timeout and forward_timeout values only result in a faster 'connection timed out response'? Is the cache_peer option for specifying parent/sibling caches only, or can I specify a web server as a peer? How would squids built-in peer monitoring gracefully handle the situation the web server host is down. i.e the web server is configured as the httpd_accel host thanks Neil On 20/03/06, Henrik Nordstrom <henrik@xxxxxxxxxxxxxxxxxxx> wrote: > mån 2006-03-20 klockan 16:30 +0000 skrev Neil Mc Lysaght: > > Hi all, > > > > Slight Problem here.. > > > > I have installed and configured squid hoping that it would provide a > > level of resillience in the event a destination server 'goes down'. > > > > Currently I have 2 squid proxies running each configured to recognise > > the other as a peer sibling. > > Each of the quid proxies is configured to use the same destination > > host configured as httpd_accel host port etc > > The Content being serverd by the destintation server sends a > > max-age/expires header in its response. > > For best results you should try to also send a Last-Modified, and even > better if you server can make use of this in If-Modified-Since... > > > My problem is that I would like the Squid proxy to continue to serve > > content even if the destination server is not available. > > Is this possible. > > It is supposed to do so if the content is refreshable, i.e. haves a > Last-Modified header. > > > but If the destiantion is not available, everything hangs and > > eventually times out. > > See connect_timeout and forward_timeout.
