As I mentioned in a previous posting (Subject: MultipartPostMethod Holding File Stream
Open?), I'm using the MultipartPostMethod to upload a file to a servlet. Here is the
example code that I included in the other posting:
> File file = new File(strUrl);
>
> HttpClient client = new HttpClient();
> HostConfiguration hostConfig = new HostConfiguration();
> MultipartPostMethod mpPost = new MultipartPostMethod();
>
> hostConfig.setHost(someURL.getHost(), someURL.getPort(),
> someURL.getProtocol());
> client.setConnectionTimeout(30000);
> client.setHostConfiguration(hostConfig);
>
> mpPost.addParameter("someName", "someValue");
> mpPost.addParameter(file.getName(), file);
>
> mpPost.setPath(strPath);
> client.executeMethod(mpPost);
>
> String confirmUpload = tpPost.getResponseBodyAsString();
> mpPost.releaseConnection();
I've been uploading some small text files (about 14KB each) and it seems to work
properly in this situation. However, when I try to do the same with a 20MB file (I
realize that this is a very large file, however, I want to test it's performance) a
SocketException is thrown.

Is there some kind of cap on the file size that I can send? If so, at what size is
the cap set?
