Domains used by the Predefined SaaS Application Types

List of domains you use for header insertion rules when using predefined HTTP header insertion rules.
SaaS applications use HTTPS so, to insert custom headers into this traffic, custom headers must be decrypted. If you use the forward-proxy decryption available on the firewall to decrypt custom headers, you must identify the specific HTTPS traffic you want to decrypt by identifying the domains associated with the traffic. The following table identifies the relevant domains for each of the SaaS applications for which Palo Alto Networks® has provided predefined rules.
