4.4: System.Net.HttpWebListener
4.4 System.Net.HttpWebListener
In .NET 2 Whidbey, a more elegant solution for implementing Web servers exists, namely the HttpWebListener class. This class leverages the Http.sys driver (where available) to deliver unprecedented performance, and integrates many features, such as SSL encryption and authentication, which would be difficult to develop from the ground up.
The HttpWebListener class consists of the significant methods and properties shown in Table 4.7.
| Method or Property | Description |
|---|---|
| Abort / Close | Destroys the request queue. |
| AddPrefix | Adds a prefix to the Web listener. |
| BeginGetRequest | Awaits a client request asynchronously. Returns IasyncResult. |
| EndGetRequest | Handles client request. Returns ListenerWebRequest. |
| GetPrefixes | Retrieves all handled prefixes. Returns String[]v. |
| GetRequest | Awaits a client request synchronously. Returns ListenerWebRequest. |
| RemoveAll | Removes all prefixes. |
| RemovePrefix | Removes a specified prefix. |
| Start | Starts the Web server. |
| Stop | Stops the Web server. |
| AuthenticationScheme | Sets the means by which the server authenticates clients. Returns AuthenticationScheme (i.e., Basic, Digest, NTLM). |
| IsListening | Determines if the server is running. Returns Boolean. |
| Realm string | If Basic or Digest authentication schemes are selected, gets the realm directive. Returns String. |
The ListenerWebRequest returned by GetRequest contains the significant methods and properties shown in Table 4.8.
| Method or Property | Description |
|---|---|
| Abort / Close | Closes the client connection. |
| GetRequestStream | Retrieves a reference to the stream sent from the client. Returns Stream. |
| GetResponse | Retrieves a reference to the response to be sent to the client. Returns ListenerWebResponse. |
