Existing Infrastructure
Proxy Servers / Firewalls
Administrators can effectively filter GENA message by using any of:
- HTTP Extension ID (Mandatory)
- HTTP Method
- Resource URI / Call-back URI
- When policy allows, existing proxies/firewalls can already deal with GENA/HTTP messages
Mail Servers
- mailto callbacks end up in mailbox
- Simple filters (procmail, exchange) can process incoming event notifications
