Setting up custom error pages for Umbraco can be a bit of a pain sometimes. Especially if you want the content to be editable through the CMS, and use the same templates you use for your content pages.

I came up with a nifty solution and thought I'd share.

You can find the full explanation and a sample project here: https://github.com/dimi3tron/Umbraco.CustomErrors

The project demonstrates how you can set up custom error pages in a few easy steps. If possible the content and templates for these pages will be loaded from Umbraco. Of course there is also a fallback scenario for those cases when an error occurs in Umbraco itself.

Features:

• Configure content of the error pages in Umbraco
• Configure templates of the error pages in Umbraco
• Returns appropriate http status codes
• Works in multi domain setup
• Handle 404's the easy way (no more messing with custom content finders)
