Plack::Middleware::CookieMonster - Eats all your (session) cookies in case Plack::Middleware::StrackTrace ate your HTTP headers.


 # Only expire selected cookies
 enable 'CookieMonster', cookies_names => [ 'session_cookie', 'foobar_cookie' ];
 enable 'StackTrace';

 # Only expire selected cookies on a certain path
 enable 'CookieMonster', cookies_names => [ 'session_cookie', 'foobar_cookie' ], path => '/foo';
 enable 'StackTrace';

 # Expire all cookies the browser sent
 enable 'CookieMonster';
 enable 'StackTrace';


When developing a plack application with Plack::Middleware::StackTrace enabled, you may sometimes find yourself in a situation where your current session for your webapp is borked. Your app would usually clear any session cookies in that case, but since Plack::Middleware::StackTrace will simply throw away any HTTP headers your app sends, you'll be stuck to that session.

Plack::Middleware::CookieMonster will detect that Plack::Middleware::StackTrace rendered a stack trace and will add Set-Cookie headers to the response so that the cookies you configured or all cookies that the browser sent will be expired.

This middleware was written because I was too lazy to search the "clear cookies" control in my browser and because I think we should automate as much as possible.


You can provide a cookie_names parameter, pointing to an array-ref containing the names of all the cookies you want to clear. Otherwise, all cookies the browser sent will be expired.


If your session cookie comes with a path parameter, configure this middleware to expire the cookie(s) on that path. Otherwise, confusion will rule.
