How to handle ASP.NET Session State in AppHarbor

Question

As in any cloud platform as a service such as AppHarbor it is very important how to manage sessions because each user request can be handled by different server.

There are two ways:

• InProc if platform support sticky session, so user request always lands on the same server. Does AppHarbor support sticky session? I found some references that it does and some it doesn't.
• OutProc with Memcached as prefered solution which transfer session data between servers. Memcached is not supported in EU region. Why? There is third party AppHarbor Add-on but non build solution managed by AppHarbor.

So what is recommended was to handle sessions (in EU region)?

Thank you very much for your help.

Answer 1

You should just use MemCachier for EU apps. The AppHarbor support forums have details on how to get MemCachier set up for use with session state.
