I have have a nginx server serving http and https and I have varnish behind to cache the apache requests

nginx (80+443) -> varnish (6081) -> apache (8081)

when I serve pages using 443, pages are already cached with port 80 (image references etc) therefore browser alerts saying there is some encrypted and unencrypted content on the page.

I cant use relative URLS.

is there a config i can keep in vcl so that it uses different hash for https requests.

Why three tiers? It's making your site significantly slower than it need be.

No - you're just mixing HTTP and HTTPS urls on your page.

need to make 3 tiers... becoz... I need http and https, I read that varnish doesnt support https, so I have nginx on the front, otherwise I can put varnish on front. –  Murali Jan 25 '12 at 23:08
    
Varnish might not do SSL, but nginx does and also works fine as a reverse proxy. (You could use stunnel for the SSL, which eliminates the HTTP parsing, in front of varnish instead of nginx if you really want to write stuff in VCL) –  symcbean Jan 26 '12 at 11:36
