Switching to Thin server

Although a lot of rails sites are using Mongrel in a cluster mode, I've chosen to use Thin.The installation is really easy :Yourapplicationdir$\ gem install thinThen choose the i386 version when asked (at least with such a name, you're sure it's working on Windows).Usage: thin start instead of the usual ruby script/server

Some important things to know when working with Active records and SQL Server :1. The ID field has Integer as default data type 2. The ID field is automatically created with an Identity specification with the following values : - Identity Increment 1 - Identity Seed 13. The created_at field does not get a default value (eg.
