Does DNN Keep Alive can speed up other IIS Sites than DNN Portals (e.g. Share Point Portal Sites) also?
Yes! Every IIS/ASP driven Website can be kept alive and will profit from DNN Keep Alive.
I've 30 sites on same Server, can i use your Software?
Yes! The software is designed to use as less system resources as possible. Each kept alive site runs in its own thread - resulting in stablity and a responsive system, even if a request times out. How many sites you can monitor depends on your system (OS, Memory, Proc).
Does DNN Keep Alive notify me if the Site is down?
Yes! Starting with the April 2008 Release you can get an "Alert E-Mail" if one of your Sites is not accessible after a configurable number of retries.
I've many Portals on one Server. Have I to keep alive each Site/Portal or is it enough to keep one Portal alive because they are using the same resources on the server?
You have to keep each DNN Portal keep alive (and add one page of the portal to DNN Keep Alive - e.g. keepalive.aspx) - 'SubPortals' are kept alive with the 'Master Portal'. If the DNN Installations use the same AppPool (IIS 6/7) the recycle and unload process occures for each portal using this AppPool - you can think about this like a common configuration for a number of sites.
