Upload documents from other websites

Question

I want to upload documents from a ASP MVC website to my Sharepoint document library. Found a lot of websites about this topic, but most of them are focussed on uploading documents from within Sharepoint.

I found this article about uploading documents with REST, but in the source code there are references to:

_spPageContextInfo.webAbsoluteUrl

Am I missing some libraries or is there another way to upload documents from outside Sharepoint?

To upload a file to SharePoint from C# code, the best is to use the client-side C# API of SharePoint. This only requires to add two DLLs as references to your Web app project (Microsoft.SharePoint.Client.dll and Microsoft.SharePoint.Client.Runtime.dll).
