Apache Commons FileUpload

Apache Commons FileUpload was coded around the RFC 1867 standard.

This standard, also known as "Form-based File Upload in HTML" is a series of protocols and conventions regarding the handling of data during a file upload.

The Commons FileUpload component specifically addresses forms where the "multipart/form-data" encoding was used and the library exposes an API for fetching various details from the POST request received on the server.

What Apache Commons FileUpload addresses might seem trivial, but it's a must have tool for any developers that ever decides to add a <input type="file"> tag to their HTML.
