Mike,
My company is currently using the HttpClient utility in an Applet
successfully through proxy servers detected by the browser. Here is how the
proxy settings are configured:
HttpClient client = new HttpClient();
HostConfiguration hostConfig = client.getHostConfiguration();
hostConfig.setProxy(proxyHost, proxyPort);
We detect the browser proxy settings as follows:
// Retrieve Proxy Server Settings from System if specified
String proxyList = System.getProperty("javaplugin.proxy.config.list");
if (proxyList!=null && !"".equals(proxyList)){
StringTokenizer tokenizer1 = new StringTokenizer(proxyList, ";,");
if (tokenizer1.countTokens()>1){
while (tokenizer1.hasMoreTokens()){
String s = tokenizer1.nextToken();
if (s.toLowerCase().startsWith("http")){
StringTokenizer tokenizer2 = new StringTokenizer(s, "=:");
tokenizer2.nextToken();
proxyHost = tokenizer2.nextToken();
proxyPort = Integer.parseInt(tokenizer2.nextToken());
}
}
}
else {
StringTokenizer tokenizer = new StringTokenizer(proxyList, ":");
proxyHost = tokenizer.nextToken();
proxyPort = Integer.parseInt(tokenizer.nextToken());
}
}
