I'm using this, seems to work on windows using plugin 1.4 and 1.5:
/**
* Detects the proxy to use (if configured in the browser). The
return string
* is either "DIRECT" (no proxy configured) or "PROXY host:port
[;DIRECT | PROXY...]"
*
* @param url the url to find the proxy for.
* @return the proxy host or the string "DIRECT"
*/
public String detectProxyForUrl(String hostUrl) {
try {
com.sun.java.browser.net.ProxyInfo[] pi =
com.sun.java.browser.net.ProxyService.getProxyInfo(new URL(hostUrl));
if (pi == null || pi.length == 0) {
log.info("ProxyService reported NULL proxy (no proxy
assumed)");
return "DIRECT";
}
else {
log.info("ProxyService returned proxy "+pi[0].getHost()+
":"+pi[0].getPort()+".");
String host = pi[0].getHost();
int port = pi[0].getPort();
return "PROXY " + host + ":" + port;
}
}
catch (Exception ee) {
log.error("Could not detect proxy info.", ee);
}
return "DIRECT";
}

Just wondering if HttpClient is able to do automatic proxy
configuration,
i.e. steal the proxy settings from the default browser?
If not, is there any plan to implement such a feature?
Here is my own proxy detection method. It reads all info from system
properties. It works on Java 1.4.2 but on Java 1.5 doesn't because
Java 1.5 doesn't store proxy information in system properties AFAIK.
But correct me if I'm wrong.
Here's my code:
public void detectProxy(Properties p) {
ArrayList proxies = new ArrayList();
if (p.containsKey("http.proxyHost")) {
HashMap pm = new HashMap();
/*
* http.agent = Mozilla/4.0 (Mac OS X 10.4.1)
* http.auth.serializeRequests = true
* http.nonProxyHosts = www|*.www|monarakh.hu|
*.monarakh.hu|core0|*.core0|core1|*.core1|10.0.0.2|127.0.0.1
* http.proxyHost = core0
* http.proxyPort = 3128
* https.protocols = SSLv3,SSLv2Hello
* https.proxyHost = core0
* https.proxyPort = 3128
*/
try {
HashMap m = new HashMap();
m.put("host", p.getProperty("http.proxyHost"));
m.put("port", p.getProperty("http.proxyPort"));
pm.put("http", m);
} catch (Exception exc) {
// debug
System.out.println(getClass() + ": failed to set http
proxy setting, exc="+ exc);
}
try {
HashMap m = new HashMap();
m.put("host", p.getProperty("https.proxyHost"));
m.put("port", p.getProperty("https.proxyPort"));
pm.put("https", m);
} catch (Exception exc) {
// debug
System.out.println(getClass() + ": failed to set
https proxy setting, exc="+ exc);
}
// put("proxy.autodetected", pm);
proxies.add(pm);
}
if (p.containsKey("javaplugin.proxy.config.list")) {
HashMap pm = new HashMap();
/*

* javaplugin.proxy.config.list =

* javaplugin.proxy.config.type = manual
* javaplugin.proxy.usebrowsersettings = true
*/
String str = p.getProperty("javaplugin.proxy.config.list");
if (str != null) {
if (str.length() > 0) {
String[] list = str.split(",");
for (int i=0; i<list.length; i++) {
String sel = null;
String key = null;
if (list[i].startsWith("http=")) {
sel = list[i].substring("http=".length());
key = "http";
} else if (list[i].startsWith("https=")) {
sel = list[i].substring("https=".length());
key = "https";
}
if (sel != null) {
// TODO: no we have host:port pairs. take
it apart and drop into a map
String[] ops = sel.split(":");
try {
HashMap m = new HashMap();
m.put("host", ops[0]);
m.put("port", ops[1]);
pm.put(key, m);
} catch (Exception exc) {
// debug
System.out.println(getClass() + ":
failed to set http proxy setting, exc="+ exc);
}
} else {
// debug
System.out.println(getClass() + ":
unknown proxy type: "+ list[i]);
}
}
} else {
// debug
System.out.println(getClass() + ":
<javaplugin.proxy.config.list> is empty!");
}
}
proxies.add(pm);
}
put("proxies", proxies);
}
Hope it helps,
Gábor
