Heh, I&#x27;ve been using flask tempting to make some html forms for exploring large datasets. Turns out when you have 6000 terms that show up in 6 different UI elements putting those in as raw html results in a 13mb file that compresses down to 520kb. Pretty awful use case for forms. I&#x27;m pretty prejudiced against JavaScript, but having seen this I now deeply appreciate being able to send something other than raw html.
