This article is how to make a forum irrigation machine, which is tested for a large real estate forum. It is a JIVE3-based forum. If the forum has joined picture certification to log in, this program will lose its role.
This program uses httpclient package, download address: http://www.innovation.ch/java/httpclient/
The principle of irrigation machine is very simple. It is the form of the analysis forum. It can be submitted with its own procedure to simulate it. The purpose of this article is to introduce this open source tool for HTTPClient, from JDK .NET package strength, HttpClient features multiple operations Re-use the same connection, set the connection timeout (based on socket), use the proxy verification. Specifically, you can see comparison data to the Innovation website. The following is a simple program of the Irrigation program, for reference only import java.net. *; Import java.io. *; Import java.util. *; Import httpclient. *;
