Notes for class

• Watch after Three Things In, Three Things Out, which opens the three parts of an HTTP message.
• Read next: the Forms section, starting with The form and its request, which takes the same request apart field by field.
• Try it yourself: point a form at https://cse134.site/api/echo. Its answer is your own request: the method, every header, and the raw body. Client-Side Communication, step 01 walks through the same form by hand, and step 06 compares the three encodings.
• The rules: the HTML standard's form submission and entry list algorithms, and RFC 7578 for multipart/form-data.
• method="dialog" closes the dialog a form sits in and sends no request; it is left for another tutorial.
• The narration is a synthetic voice (ElevenLabs). Timing follows the narration track, so a recorded voice-over can replace it cue for cue using the transcript.
• With Reduce Motion turned on in the operating system, the film keeps its fades and drops the sliding motion.
• Set in Atkinson Hyperlegible Next and Mono, typefaces the Braille Institute designed for readers with low vision.
