I have a CentOS instance. Is it possible for multiple domains / subdomains to share that single instance and on my Apache server i will have separate folders for each domain. How do I start doing this and how would I map my subdomains to the instance.
If we scale up (add an instance to ELB), could we redirect some existing requests to the new instance. So that, The users that we force to a new server will be asked to login again
If we scale down (remove an instance from ELB), then all users from that server will automatically be redirected by ELB to other remaining servers. These user should not be aked to login again.
Is this possible (including the redirect of request)? How?
Any ideas are welcome but I presume this can be solved using a central session store. I just don't know how to implement it .
And what are the options in using a central session store? simpledb? redis? memcached?
UPDATED:
Our application is just a simple web application hosted in apache. We have two instances of it added unto the Amazon ELB, and we are using PHP.
Any ELB php specific suggestions? when a scale down/up happens that no user-visible symptomps should be shown?
Where exactly could I start creating a SimpleDB, I will be using PHP as the client. I can't find it anywhere on the AWS console.

I am trying to make AspNetComet.zip work on IIS7 (a simple comet chat implementation) Here is a portion of my web.config.
<system.web>

</httpHandlers>

The target framework of this project is .Net 2.0 I tried the Classic and Integrated Mode application pool for .Net 2.0 with no luck. I also tried converting the project to 4.0 and tried the Classic and Integrated Mode application pool for .Net 4.0 with no luck. I also tried adding the managed handler through IIS Manager's Handler Mappings.
If you have time please download the source (184kb) to reproduce the problem on your own machine. The zip contains a VS2010 solution (.Net 2.0). You could also try to convert this to .Net 4.0
I am using Windows 7 anyway if that matters. If you need more details, please drop your comments below. This is working fine by the way on my webdev server.
