Look for "Posting CGI Data"

Search for the <form ***> tags. There may be more than one. Find the
one that seems relevant to your query. The find the bracketing </form>.
If there are lots of fields, I usually edit out all the non-tag stuff,
except just enough to know what the input field is about. With all the
inputs, etc, between the <form />. You've got your base information.
Generally, JavaScript code can be ignored, as it is used to validate
fields, update other fields, etc. Keep an eye out for hidden fields
(that are not visible in the browser) as they frequently contain
critical data.

It is all "stringified" ultimately and url encoded. If there are spaces
in data, then enclose.
