how to set query string based cookie value and expire time
September 09, 2009 10:32AM
Hello,

I just migrated Apache to nginx, there is a rewrite rule to set cookie based on query string. If query string contains a parameter f=foo,then set Cookie (Key=f,Value=foo), and expire at two months later.

I use :

location / {

if($query_string ~ "([^&]*)f=([^&]*)"){ #check whether there has a 'f=xx' key/value pairs.
add_header Set-Cookie "f=$2; path=/; domain=bar.com";
}

it worked but how to set cookie expire time? It is a variable = $current_time + 60d


Best Regards.

Have you tried using the UserID module? See http://wiki.nginx.org/NginxHttpUserIdModule. Maybe that can be adapted for your needs.

Jim:

I gave a try with UserID module , It set cookie with value something like 'wKhfOkqoyBuH7n5BAwMDAg=='. But what I wanted Cookie value is extracted from request query string.

for example:

when visit http://www.foo.com/index.html?f=google , a cookie need to set to browser :

Key = f
Value = google
expires = currenttime+60d
