HTTP SSL (HTTPFilter) Service Defaults in Windows XP

This service implements the secure hypertext transfer protocol (HTTPS) for the HTTP service, using the Secure Socket Layer (SSL). If this service is disabled, any services that explicitly depend on it will fail to start.

Default Behavior

HTTP SSL is a Win32 service. In Windows XP it won't start until the current user starts it. When the HTTP SSL service is started, it is running as LocalSystem in a shared process of svchost.exe. Other services and drivers are allowed to run in the same process. If the HTTP SSL fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the HTTPFilter service has failed to start.


HTTP SSL depends on the HTTP service.
