I have two exactly the same web sites hosted in two different machines under IIS 7.5. ASP.NET state service is running on my machine and the web.config is updated in both sites with the following code:

<sessionState mode="StateServer" stateConnectionString="tcpip=192.168.1.77:42424" cookieless="false" timeout="120"/>

The allow remote connection is set to 1 in registry in order for the second web site to access the state server.

Both web sites have the same machine key:

<machineKey validationKey="7CB8DF6872FB6B35DECD3A8F55582350FEE1FAB9BE6B930216056C1B5BA69A4C5777B3125A42C4AECB4419D43EC12F168FD1BB887469798093C3CAA2427B2B89" decryptionKey="02FC52E4C71544868EE297826A613C53537DF8FDAF93FA2C64E9A5EF0BA467FB" validation="SHA1" decryption="AES" />

Additionally both sites are configured in IIS to have the same Identifier.

What I want to do is that both these sites share the same session data for example being able to do the following:

// At web site 1: 
Session["key"] = "value"

and 

// At web site 2:
// Read session value from the other web site
string result = Session["key"]

The problem is that I can't manage to accomplish this test and really can't understand what I am doing wrong.

Any idea that might help?

My issue was that my two applications were using different major versions of the Owin libraries. Once I ensured all Owin libraries between the two applications shared the same version, I was able to get this to work by following the answer posted by Hoàng Long.

In addition to what has already been said, the application name matches the IIS website id: \LM\W3SVC\<id>\

To share a session between two website, ensure the application have the same id in IIS on all your servers. This id can be changed in the site Advanced settings > (General) ID.
