Свойства

	Имя	Описание
	BypassProxyOnLocal	Gets or sets a Boolean that indicates if the proxy server is configured to use credentials and bypass the proxy server and use local addresses instead.

Замечания

The HTTP connection manager allows packages to access resources over HTTP, allowing tasks such as extracting data from a Web service and operating on it. The HTTP connection manager encapsulates the functionality of creating and maintaining a HTTP connection. The HTTP connection manager includes custom properties, in addition to the properties that are common to all connection managers. The HTTP connection manager provides the runtime with a connection to a HTTP server that acts as a source. When you create an HTTP connection manager, you can specify properties specific to that connection and test to see if the connection is alive. After the connection has been created, the connection can be used by various tasks in the runtime.

This class inherits from DtsObject and implements IDTSPersist.
