ending simple GET requests from Java is extremely easy (be it an application or a servlet), but sending multipart forms, like when you upload files, is painful. The former can be done in one method call that does all the underground work. The latter requires explicitly creating an HTTP request, which may include generating multipart boundaries while being careful with the exact amount and selection of newlines (e.g., println() would not always do the right job).

The intention is to make POST requests as simple as GET requests, even when sending multiple files of varying type (archives, XML, HTML, plain text, etc.).
