Role of AllowUnsafeUpdates

Explain the role of AllowUnsafeUpdates.

- AllowUnsafeUpdates allows updates on a GET request.
- It basically allows code to bypass security validation while making changes to Sharepoint objects which are not executed within a HTTP POST request.
- It will get or set a Boolean value that will specify whether to allow updates to the database as a result of a GET request or without requiring a security validation.
- We need to set SPWeb.AllowUnsafeUpdates = true whenever the code modifies the SharePoint data in some way or whenever an update is needed on the SharePoint objects like SPWeb, SPList, SPListItem etc without requiring a security validation.
