Hosting a .NET Remoting object in IIS

Microsoft Internet Information Server (IIS) can be used to host .NET Remoting objects, simply by installing the remoting server’s executables in an IIS virtual directory.

HTTP channel

The channel, for communication between remote components, that uses the familiar Hypertext Transport Protocol (HTTP) to pass data. By default, the HTTP channel uses the Simple Object Access Protocol (SOAP) formatter to send the message call as an XML document.

Hypertext Transfer Protocol (HTTP)

An application-level protocol by which text and other types of data can be transferred over the Internet. HTTP is supported on all platforms. HTTP traffic is usually allowed to move through corporate firewalls with little interference on well-known port 80.

Identity object

imperative

A term used to describe techniques for specifying an application’s security features that are implemented directly in the application’s source code. Contrast this with the declarative technique of applying attributes to assemblies, classes, or methods.

impersonation

Enables a process to temporarily take on the identity of another user, whose authorization to perform certain tasks might be different from the user identity under which the process was created.

InsertCommand

This property of the ADO.NET DataAdapter class is one of the three related properties that hold the SQL statements (or stored procedure names) that will be used when the corresponding insert, update, or delete operations must be performed during an update to the database.

InstallUtil.exe

instance

instrumentation

The process of adding features to your applications that provide the ability to measure performance and to track and troubleshoot errors.

integration testing

A type of testing used to ensure that calls are being made correctly to your component and that the return results are in the correct format. Integration testing tests the interface between two components.

IsolationLevel property

A property of the ADO.NET Transaction class that can be set to request that the database server place a high level of isolation, or protection, against other users changing (or even reading) the same data that your transaction is working with.

just-in-time-activation (JTA)

A feature that enables COM+ to activate an object instance very quickly when a client application makes a call on an object. When that method call is complete, COM+ can also quickly deactivate the object instance and release any memory or other resources that the object is holding. By releasing these resources quickly, they can be made available to other users.

lease manager

A part of the .NET remoting architecture, this object is responsible for locating client-activated objects whose lifetime lease has expired and marking them as available for garbage collection.

lifetime lease

The predetermined lifetime of client-activated remoting objects or the amount of time they will remain active on the server if there are no incoming calls from the client. The lifetime lease can be extended at each client call, or to a specific amount of time by the client.

Load method
