Asp Forum - Factory and CAO lifetimes - microsoft.public.dotnet.framework.remoting

Im looking for information on how lifttime is managed in a factory
situation.

My basic question is in regards to a webapplication calling the singleton
and thus instantiating a CAO. I am using Activator.CreateObect(). I am
windering if the CAOs will be destroyed when the ASP,NET webforms have
finsihed executing. This is desired since I dont need a bunch of objects
hanging around on the server with every page request that gets called. I
need a way for a webform to create the obect and then destroy it soon as the
web form becomes disconnected. (Does this happen automatically by the
remoting framework or do I need to add logic)

Thanks in advance

With a Client Activate Objects (CAO) you either have to override the
InitializeLifetimeServices method:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemmarshalbyrefobjectclassinitializelifetimeservic...

Or define a sponsor. Check out this article for an in-depth discussion:

Managing the Lifetime of Remote .NET Objects with Leasing and Sponsorship
http://msdn.microsoft.com/msdnmag/issues/03/12/LeaseManager/de...

If you want to have a Factory return SAOs you can do that as well. There
was a discussion a while back in this newsgroup and you can see an example
on my site: http://www.softitechture.com/d....

Thanks,

Sam

So it seems that the CAO will not recognize on its own that the client (in
this case a asp.net application webform thread) has finished? I guess this
is what I was getting at.

Thanks!
