HttpClient
provides a
simple "user-agent" implementation that will suffice for many
applications, but whose use is not required.
HttpClient also provides several utilities that may be
useful when extending the framework:
HttpMethodBase
HttpStatus
ChunkedOutputStream
java.io.OutputStream
ChunkedInputStream
java.io.InputStream
URIUtil
-Dname=value
command line arguments to the application that uses HttpClient.
These properties can also be set programaticly by calling
System.getProperties().setProperty(name, value)
.
This is the list of properties that HttpClient recognizes:
Name | Type | Effect |
---|---|---|
httpclient.useragent | String | Sets the User-Agent string to be sent on every HTTP request. |
httpclient.authentication.preemptive | boolean | Sends authorization credentials without requiring explicit requests from the web server |
