Setting a region cookie

[Nicolas Delmas]

Hi,

Be careful the method in the link given by Michael doesn't work.
To set a cookie, you must use the vmod header.

And in the subroutines *vcl_deliver* you must add sotmehting like this
(just change the name of the cookie and the value)

header.append(resp.http.Set-Cookie,
> "VarnishCache="+resp.http.X-Cache+"path:/");



Because using the set resp.http.Set-Cookie = overwrite all Cookie written
by the backend.


I just implement this method in my website to get Analytics stats of my
Varnish
