Description

I have an application which sets a cookie of the form app.current.user.id and I'm attempting to use that with proxy_cache_bypass etc, but it seems nginx can't process that cookie.

config snippet:

location /test {
    return 200 'http_cookie=$http_cookie cookie_app.current.user.id=$cookie_app.current.user.id cookie_control=$cookie_control\n';
}

test:

$ curl -b "app.current.user.id=MjAxNS0wMS0yOFQxNDoxNTo0M1pYM0ZUSFBZOXVhQTh2c3Z4MlJMWDQ3;control=works" https://server/test -k
http_cookie=app.current.user.id=MjAxNS0wMS0yOFQxNDoxNTo0M1pYM0ZUSFBZOXVhQTh2c3Z4MlJMWDQ3;control=works cookie_app.current.user.id=.current.user.id cookie_control=works

Variable names recognized by nginx are limited to alphanumeric characters and '_', so you can't use special $cookie_... variables to access cookies with '.' in their names. If needed, you can access such cookies using the $http_cookie variable (e.g., by using map with regular expressions).

Note: See TracTickets for help on using tickets.
