This is fairly high, but I'm not
sure just how high. If you're
concerned your query strings will get cut off, use POST instead of
GET.
page title
255 bytes (MediaWiki-enforced
limit). This does NOT include the namespace prefix
page content (wikitext and HTML versions)
The wikitext limit is configurable. On Wikipedia this is 2000 KB.
Except a few old pages that are longer.
HTTP response
from server
No limit.
edit token
login token
Always the same length, don't recall the exact number offhand. We
may
make it longer without announcement if needed, though.
They are currently 34 characters for logged in users.
username
255 bytes, as usernames are also titles.
