The following roles are deployed to Windows Azure Cloud Services.

The application needs session stickiness, so we have deployed Web Farm Framework and ARR.

Also the application needs .NET 4.5 to run. Because of this I have to deploy to Windows 2012.

But...Web Farm Framework is not available for Windows 2012 / IIS 8.

Question:

Are there any other ways to implement a "sticky session router" on Windows Azure?

Or any workaround or other ideas?

hello, 

Please see this blog http://coderead.wordpress.com/2011/09/12/sticky-sessions-and-windows-azure/ 

Hi

I think the best solution is to use Azure cache.

Create a cache service (or in-role) and assign your site configuration session to store information over the cache.

more information can be found here :

Thanks,

In our case the session state is not serializable so we cannot use a caching mechanism.

Moving to a stateless application is also not an option because we use 3rd party components that are state aware and cannot be changed.

The solution that we are using is this one:

But unfortunately this does not work on Windows 2012 / IIS8 so we are looking for another similar solution.

Unfortunately we cannot use caching.

Thank you for your suggestions..

XAF still does not support this and will not support this in the future. We had a look at the source code but it was too complex (for us) to make any changes that would make this possible.

When we try to deploy to Windows 2008 we get the following error message:

The feature named NetFx45 that is required by the uploaded package is not
available in the OS * chosen for the deployment.

I assumed this was checked before the OS was prepared but maybe I am mistaken. I will try to install .NET 4.5 using a startup task.

I will have a look at the link that you provided. Thank you for your input.
