can one iis worker process have many application domain?

can one iis worker process have many app开发者_如何学运维lication domain? if does then what if one of the application fails, will it affect the other application running using same worker process?

in other words i have read in many articles that if one of the application sharing same app pool fails then it does affect other application in that pool

however, i also read that one process can have many appDomain (one for each application) and if one application fails it does not effect other application in that process

a bit confused

Yes, if an apppool shared by multiple websites is stopped intentionally or due to some other failure (and it doesn't restart automatically) all the websites sharing that apppool will be stop working.

Yes an apppool can service many domains, either as separate sites, or multi-tennanted in the same site.
