Getting exception: Unbuffered entity enclosing request can not be repeated

[Jennifer Ward]

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
