I have made a simple web application, based on Java and Spring, which can be used for testing various aspects of HTTP.

There are forms to test HTTP GET and HTTP POST, and forms for testing file upload and HTTP POST multipart/form-data, all using various content/character set encodings

The test application is available here. Note that the japanese encoding has not been testet much.
