copied!<p>Not the solution, but more of an explanation of what is going on.</p> <p>What you are doing is correct. </p> <p>First of all, if you are using Log4J, make sure you see everything that HttpClient wants to show you:</p> <pre><code>log4j.logger.org.apache.http=trace </code></pre> <p>Then take a look at this class:</p> <p><a href="http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/conn/DefaultClientConnectionOperator.html">http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/conn/DefaultClientConnectionOperator.html</a></p> <blockquote> <p>This connection operator is multihome network aware and <strong>will attempt to retry failed connects against all known IP addresses sequentially until the connect is successful or all known addresses fail to respond.</strong> Please note the same CoreConnectionPNames.CONNECTION_TIMEOUT value will be used for each connection attempt, so in the worst case the total elapsed time before timeout can be <strong>CONNECTION_TIMEOUT * n</strong> where n is the number of IP addresses of the given host.</p> </blockquote> <p>That's what most likely is happening in your case.</p> <p>Also, it is better to use constants from this interface <strong><a href="http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/params/CoreConnectionPNames.html">HttpConnectionParams</a></strong>:</p> <pre><code>SO_TIMEOUT = "http.socket.timeout" TCP_NODELAY = "http.tcp.nodelay" SOCKET_BUFFER_SIZE = "http.socket.buffer-size" SO_LINGER = "http.socket.linger" SO_REUSEADDR = "http.socket.reuseaddr" CONNECTION_TIMEOUT = "http.connection.timeout" STALE_CONNECTION_CHECK = "http.connection.stalecheck" MAX_LINE_LENGTH = "http.connection.max-line-length" MAX_HEADER_COUNT = "http.connection.max-header-count" MIN_CHUNK_LIMIT = "http.connection.min-chunk-limit" </code></pre> <p>You need only two of them:</p> <pre><code>HttpConnectionParams.CONNECTION_TIMEOUT HttpConnectionParams.SO_TIMEOUT </code></pre> <p>So the best way to solve this is to implement a custom <strong>ClientConnectionOperator.resolveHostname</strong> method that returns only one IP address.</p>
