Chapter 1 What’s New for FortiOS 5.0 : New features in FortiOS 5.0 Patch 4 : Distinguishing between HTTP GET and POST in DLP

Data Leak Prevention (DLP) can now distinguish between HTTP GET and POST protocols, allowing the protocols to be selected independently.
HTTP POST protocol can be examined by both message and file filters, while HTTP GET can only be used for file filters.
