---------------------------------------------

Aah. Sorry, should have done that first. The problem appears resolved. 

Thanks
Michael

> Components: HttpClient
> Affects Versions: 4.0 Alpha 4
> Environment: Linux, java version "1.6.0_06" Java(TM) SE Runtime Environment (build \
> 1.6.0_06-b02) Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode). Also using \

> "org.apache.http.ProtocolException: Content-Length header already present" is \
> incredibly misleading.  A simple-ish compileable program to reproduce the bug is as \
> follows: import java.nio.charset.Charset;
> import org.apache.http.HttpResponse;
> import org.apache.http.client.methods.HttpPost;
> import org.apache.http.client.params.ClientPNames;
> import org.apache.http.client.params.CookiePolicy;
> import org.apache.http.entity.mime.MultipartEntity;
> import org.apache.http.entity.mime.content.StringBody;
> import org.apache.http.impl.client.DefaultHttpClient;
> public class Simple {
> static public void main(String [] args)
> {
> try
> {
> DefaultHttpClient client = new DefaultHttpClient();
> client.getParams().setParameter(
> ClientPNames.COOKIE_POLICY, CookiePolicy.BROWSER_COMPATIBILITY);
> MultipartEntity entity;
> StringBody stringBody;
> HttpPost post;
> HttpResponse response;
> entity = new MultipartEntity();
> stringBody = new StringBody("field contents",Charset.forName("ISO-8859-1"));
> entity.addPart("field", stringBody);  
> post = new HttpPost("http://localhost/simple.php");
> post.setEntity(entity); 
> response = client.execute(post);
> 
> //The exception does not occur if the content is not consumed
> response.getEntity().consumeContent();
> System.out.println("First post done");
> 
> //The exception does not occur if the time interval between the requests is too \
> short Thread.sleep(15000);
> 
> //The exception naturally doesn't occur if a new HttpClient is created
> //client = new DefaultHttpClient();
> entity = new MultipartEntity();
> stringBody = new StringBody("field contents",Charset.forName("ISO-8859-1"));
> entity.addPart("field", stringBody);  
> post = new HttpPost("http://localhost/simple.php");
> post.setEntity(entity); 
> response = client.execute(post); //Will throw the following:
> /*
> org.apache.http.ProtocolException: Content-Length header already present
> at org.apache.http.protocol.RequestContent.process(RequestContent.java:70)
> at org.apache.http.protocol.BasicHttpProcessor.process(BasicHttpProcessor.java:290)
> at org.apache.http.protocol.HttpRequestExecutor.preProcess(HttpRequestExecutor.java:160)
>  at org.apache.http.impl.client.DefaultClientRequestDirector.execute(DefaultClientRequestDirector.java:356)
>  at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:501)
