Maybe my terminology was incorrect. When I logged into the website via Chrome, that was the data listed under the "Form Data" section of the Network->Headers section of the Chrome Developer Tools.

:) Well, your terminology appears correct ... form data usualy comes delimited with "=" where as headers are delimited with ":" ... the data you've shown has two:two:two ... that confused me a bit ... I don't have chrome :)

I only know a little bit, but that was kind of why I was asking this question. How would I figure out what the website is doing?

:) I already explained -- I'd do it by figuring out and knowing what the javascript does and the way it does it -- this means I'd read the javascript program -- try a few of the functions (firefox ctrl+shift+k or ctrl+shift+j ) -- the open source version of reverse engineering

lots of time they just fetch this var, fetch that one, do some simple substitution/addition ... sometimes they md5 or sha256 some part and set a new variable ... sometimes its considerably more pointless contortions (esp difficult to discern when they use jsmin type compressors)

The only part I really don't understand is the ANTI_CSRF_TOKEN.

Its just another form variable , its given to your browser to prevent replay attacks and session riding... CSRF ... https://www.owasp.org/index.php/Session_Management#Page_and_Form_Tokens , Cryptographic nonce, Plack::Middleware::CSRFBlock
