Dear All,
I referred this article http://www.shillier.com/archive/2013/03/26/uploading-files-in-sharepoint-2013-using-csom-and-rest.aspx for uploading documents to SP Document Library and it works fine for any document library under the root site collection( for example "http://<server name>/Shared Documents" but when i upload the same document to one of the sub site collection created using Managed Path( the site collection path is "http://<server name>/files/Case" and the library name is "records") it fails and i get below error:
The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again, Error Code -2130575251 Microsoft.SharePoint.SPException"
Any help suggestion to resolve this? I've almost tried everything to resolve this issue but no luck.. appreciate any help for this..
Regards,
Vishal
