I recently had a similar needing. I did a 'fastdelete' script, avoiding to
confirm the deletion.

To have the EditToken available, it rememberes it (the edittoken is the same for
the session) at edits/deletes, on a cookie

Caching - why? I thought it was generated once during each session.

As I said in comment 1, we might like to alter things so tokens are regenerated
more often. Tokens for different operations are also salted, and so can vary
according to the operation in question. Your browser will attempt to cache the
page, including the script.

The whole point of an edit token is to help prevent malicious form submission
hijacking; I'm not convinced that providing an edit token on every page via
JavaScript wouldn't partly defeat the purpose of it.

Just to document it:
The only token which is currently different is the rollback one, which is hashed
with the user you're reverting.

The editToken is also unrelated to the ___Token cookie, used for login.

That is incorrect.

Resolving as WORKSFORME. The edit token can be obtained from the API using AJAX, or scraped from the hidden form field if you happen to be on the edit form.

API URL: http://en.wikipedia.org/w/api.php?action=query&titles=Main_Page&prop=info&intoken=edit
(append &format=whatever to get a different format; for help, see http://en.wikipedia.org/w/api.php )

(See [[Wikipedia:WikiProject_User_scripts/Guide/Ajax]] for a tutorial on doing so with JavaScript.)
