I'm not sure if this improper usage of Varnish or not, but I'd like to do the following for high availability purposes:<div><br></div><div>I have a page that's dynamic in nature, but I want to be able to serve a cached copy of it if the backend servers happen to go down. </div>
<div><br></div><div>Is it possible to do this while setting the beresp.ttl to 0? This seems to prevent grace mode and works fine if I set it to 1 (as well as if I set the relevant grace mode params), but showing people a cached page for even one second won't work right now because each load should save new data to a database. If the backend servers go down, it's okay if we aren't able to save the data -- we want to at least be able to display a cached copy of the page.</div>
<div><br></div><div>That said, perhaps Varnish isn't meant for this -- any suggestions?</div><div><div><br></div><div>Thanks!</div><div>-Victor</div><div><br></div></div>
