I worked for a now-defunct leading-edge Web development firm 1996-7. I and other programmers did this with Web-browser cookies only we called it "pickling" because our shop was heavily into Python and that's the Python term. Here's how the Python Library Reference describes the function: '"Pickling" is the process whereby a Python object hierarchy is converted into a byte stream, and "unpickling" is the inverse operation, whereby a byte stream is converted back into an object hierarchy. Pickling (and unpickling) is alternatively known as "serialization," "marshalling," or "flattening," however, to avoid confusion, the terms used here are "pickling" and "unpickling."' It didn't take any great intellectual leap to apply this technique to cookies and we did.
