Hello, Our lightspeed 4.2.4 server is configured to cache from our caching server (Server>External App>caching web sever). everything works fine when lsws server has a connection to our caching server, but if the connection breaks then the website (from the chacing on the lsws) will load very very slowly and after ~2 minutes we receive 503 "Service Unavailable" error. So it does cache but it loads the site at a very slow speed, and after a few minutes we get the 503 error. We want that if the connection between lsws server and the caching server breaks, that it will take the recent website from it's cache and use it. I've tried to play with the caching times, but it didn't solve it. Suggestions? Thanks Maxim.
