Re: The abort operation is close the socket

Could you tell me whether abort the is the only way to do for the case,or has a better one? Raymond Raymond, I do not think classic I/O model is applicable for this scenario. Consider using NIO (non-blocking I/O) instead. Oleg - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Handling proxies and modifying request header fields

My concerns are, i) The applet should be able to send requests to external websites thru the proxy (if any proxy exists). ii) The applet should be able to modify the request header fields, such as User-agent field. When I try using normal URLConnection from java.io package, the applet is able to inherit the proxy settings from the browser and send the requests thru that proxy. But, I am getting response code 403 for some of the sites. Can anybody tell me, is this possible by using Apache HttpClient?. No, it is not. You have configure HttpClient manually either using system properties or ProxySelector class if running on JRE 5.0 or newer. Oleg And if so, please specify the version.

Re: Getting the response time for multithreaded client

We are using the Commons HttpClient in a multithreaded application, and frequently there are more threads trying to use the client than the limit set by setMaxConnectionsPerHost. In this situation we still need to log the response time from the server. How can we do that? Measuring the Method.executeMethod call includes the time the thread sleeps before actually submitting the request. We are currently using Commons HttpClient 3.1 which I believe is the latest stable release. Uwe, There is no way around either upgrading to HttpClient 4.0, which has a massively better, modular architecture or hacking the source code of HttpClient 3.x Oleg Any help is greatly appreciated, even quick fixes and hacks :) Uwe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thanks very much,

The code seems okay. The wirelog seems to indicate an authentication
failure due to invalid credentials. Please double-check values of the
username, password, domain and host.
Oleg
My code is below:
*
public static void main(String args[]) {
Provider prov = new BouncyCastleProvider();
Security.addProvider(prov);
String url = http://www.google.com;;
HttpClient client = new HttpClient();
client.getHostConfiguration().setProxy(proxyHost, proxyPort);
Credentials defaultcreds = new
NTCredentials(userName,password,proxyhost,domain);
client.getState().setProxyCredentials(AuthScope.ANY,defaultcreds);
HttpMethod method = new GetMethod(url);
method.setDoAuthentication( true );
int statusCode;
try {
statusCode = client.executeMethod( client.getHostConfiguration(),
method,client.getState());
System.out.println(Stat= +HttpStatus.getStatusText(statusCode));

Re: Apache HttpClient - Using custom socket factory for failover support
On Thu, 2008-03-20 at 22:05 -0700, Ankur Shah wrote: I am using httpclient to connect to a remote server. Now for each primary server there's also a backup failover server that i must talk to if connection attempts with the primary server fails. To achieve this what i'd ideally like to do is have HttpClient use a custom factory that tries to create a socket connection with the primary server and if that fails (or times out), it'll go about talking to backup server (and retry a few times before giving up altogether). Now, searching on the web, i did find references to a MultiHomeProtocolSocketFactory (that extends DefaultSocketFactory) that is presumably in apache contrib package. But what that does is that in the overriden createSocket method, it takes host as a param (among other thing) and then simply does a InetAddress.getAllByName which is not what i want. From what i understand this caters to a DNS based failover which is not the case here. What i'd ideally like to do is create a factory and have a createSocket method that takes primary and secondary host and port as args and then tries both. I am not sure though how can i make HttpConnection class invoke my method. Ankur, What's the point of trying to implement the failover support on the ProtocolSocketFactory level? What's wrong with just retrying failed requests against a secondary server in case the primary one is unavailable?

httpclient3 takes 3 minutes to catch IOException, why so long?
Greeting...
I use httpclient3 to communicate with a web server application.
when I test an error handling, it takes 3 minutes to catch the IOException (I
manually unplug the internet connection). I assumed it takes couple ms to catch
IOException since only one line of code/function-call there
(client.executeMethod(method) to cause the IOException, but it takes 3 minutes.
It seems sth. inside executeMethod is doing sth.
Could some experters provide an inside about why it taks so long, and how to
make it quicker to catch the exception?
(note: I have set the retryhandler to 0 retry. I just want to find the IO
problem asap.)
the code is sth. like:
.
HttpClient client = new HttpClient();
PostMethod method = new PostMethod(http://www.x.com;);
NameValuePair[] data = {
};
method.setRequestBody(data);
// do not want to retry, so set to 0.
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
new DefaultHttpMethodRetryHandler(0, false));
try {
// Execute the method.
int statusCode = client.executeMethod(method);
if (statusCode != HttpStatus.SC_OK) {
}else{
...
}
} catch (HttpException e) {
...
} catch (IOException e) {
...
} finally {
// Release the connection.
method.releaseConnection();
}
Thank you,
Ever
