> Hello I am getting an exception when I try to download certain files.
> I don't have control over the host server, only the client. Here's my client code:

> params.setParameter(ClientPNames.HANDLE_REDIRECTS, true);
> // This client indicates to servers that it will support 'gzip'
> // and 'deflate' compressed responses.
> ContentEncodingHttpClient.setDefaultHttpParams(params);
> ContentEncodingHttpClient client = new ContentEncodingHttpClient();
> if (user != null && password != null) {
> String hostname = url.getHost();
> HttpHost hostHttp = new HttpHost(hostname, 80, "http");
> HttpHost hostHttps = new HttpHost(hostname, 443, "https");
> client.getCredentialsProvider().setCredentials(
> new AuthScope(hostname, 80),
> new UsernamePasswordCredentials(user, password));
>
> client.getCredentialsProvider().setCredentials(
> new AuthScope(hostname, 443),
> new UsernamePasswordCredentials(user, password));

> // Create AuthCache instance
> AuthCache authCache = new BasicAuthCache();
> // Generate BASIC scheme object and add it to the local auth cache
> BasicScheme basicAuth = new BasicScheme();
