Local IP binding
Hi All!
Could anyone describe me how to bind HttpClient to local IP addr? I mean,
I have a host with some IPs assigned to it, and I need to send
http-requests from only one specific IP.
How can I do it?

Andrew,
A custom HostConfiguration should also do the trick
HttpClient httpagent = new HttpClient();
HostConfiguration hostconf = new HostConfiguration();
hostconf.setHost("www.yahoo.com");
hostconf.setLocalAddress(InetAddress.getByAddress(new byte[] {127, 0, 0, 1}));
HttpMethod method = new GetMethod("/");
try {
httpagent.executeMethod(hostconf, method);
if (method.getStatusCode() == HttpStatus.SC_OK) {
System.out.println(method.getResponseBodyAsString());
} else {
System.out.println("Unexpected failure: "
+ method.getStatusLine().toString());
}
} finally {
method.releaseConnection();
}
Hope this helps
Oleg

HttpClient uses a ProtocolSocketFactory to create connections to the
server:
http://jakarta.apache.org/commons/httpclient/apidocs/org/apache/commons/httpclient/protocol/ProtocolSocketFactory.html
By implementing your own protocol socket factory, you should be able to do
everything socket-specific using the standard Java socket API.
hope that helps,
Roland
