Yes, HttpClient will buffer the content if you use CONTENT_LENGTH_AUTO.

The problem is that you are using chunked transfer encoding. This

the InputStream can only be read once.

The workaround is simply to provide the exact content-length.

Hi,

I wonder if anyone could offer a suggestion for getting around an
exception I'm seeing.

I am writing a load test client that sends requests to a webdav server.
I have a putMethod which does the following:


                        PutMethod method = new 
PutMethod(URIUtil.encodePathQuery(path));
                        generateIfHeader(method);
                        if (getGetContentType() != null && 
!getGetContentType().equals(""))
                                method.setRequestHeader("Content-Type", 
getGetContentType());
                        
method.setRequestContentLength(PutMethod.CONTENT_LENGTH_CHUNKED);
                        method.setRequestBody(bis);
                        int statusCode = client.executeMethod(method);

bis is a BufferedInputStream.

This method works fine when sending requests using Basic
authentication. However, I want to use Digest authentication (I have
setAuthenticationPreemptive set to false). When sending the request
using Digest, I get the exception:

org.apache.commons.httpclient.HttpException: Unbuffered entity
enclosing request can not be repeated.

In looking at the code, it appears that
EntityEnclosingMethod.writeRequestBody does not cache the request body.
So, when the request is resent (with the digest auth header), the
contentCache is null, thus the exception.


Does anyone know of a way around this?

Thanks,
Jennifer
