Understand SaaS Custom Headers
Understand the custom HTTP headers you will use before you create HTTP Header Insertion Rules for your Palo Alto Networks® firewall.
Before you begin, make sure you understand the custom HTTP headers you will use with the SaaS application you are managing. You need to understand what you can accomplish with these headers and the information you need to specify to accomplish your goals.
Be aware that SaaS applications that use custom headers do not always use them to control access to types of accounts. For example, Palo Alto Networks® provides predefined support for YouTube custom headers that determine whether network users can access restricted content.
You should also read the documentation specific to the SaaS application to which you want to control access so that you understand the headers you need to use for that application.
The following table lists the headers that you can use for the SaaS applications for which Palo Alto Networks provides predefined support; each header also includes a link to more information specific to that header.
