Forum: NGINX Redirecting based on cookie value

Hi,

I'm want to redirect the user based on the value of a cookie, if
present.

The scenario is one where there is a "starter" homepage for first time
users. As soon as users login, I write a cookie with the relative path
of another homepage. If the cookie is present, I want to redirect the
user to the cookie value: the relative path. There are multiple cookies
present in the request, such as session cookies.

I could of course, let the homepage be determined on the session on the
app server side, but since this is the landing page, I prefer to support
it with nginx reverse proxy caching. Hence the idea of using cookies to
redirect the user once he has logged in once.

Any ideas?

Marc

Use map: http://nginx.org/en/docs/http/ngx_http_map_module.html

Here's a gist that implements a system where a user is redirected to a
HTTPS host if there's a session cookie. This is "blind" in the sense
that it doesn't capture any value of the cookie. But you can do that
easily with named captures in map.
