ExemptRegexps doesn't work about nosurf HOT 3 CLOSED

It is working - there's no Set-Cookie header. It's just that your cookie
path is likely (the default of) "/", which means that your browser sends
the cookie on any response. You can either:

a) Set a more precise path for your cookies
b) Use a different domain for your static assets

oops, Ok, thanks Matt.

To clear it up: Set-Cookie will still get sent even on exempted routes, but only when the existing token in Cookie is missing or invalid: ServeHTTP() returns early only after checking the presence of the cookie.

To test whether the routes were successfully exempted, issue a POST /js/. It should not prevent the request from happening, even though the form data contains no token.

Though I think you forgot asterisks for css and js routes: a period will only match one symbol.
