hashing based on cookie combinations

[Nitin Pawar]

Hi,

I am trying to put varnish cache server infront of my apache server to
accelerate the performance.

I want to cache the data based on few cookies

I have tested with single cookie and it does work

but I have an use case where i need to cache the data based on combination
of cookies


use case

if( req.http.Cookie ~ "Cookie1" && (! req.http.Cookie ~ "Cookie2")) {
        set req.http.X-Varnish-Hashed-On =
            regsub( req.http.Cookie, "Cookie1=([^;]*);*.*$", "\1" );
    }
if( req.http.Cookie ~ "Cookie1" &&  req.http.Cookie ~ "Cookie2") {
        set req.http.X-Varnish-Hashed-On =
            regsub( req.http.Cookie, "Cookie1=([^;]*);*.*$", "\1" )+regsub(
req.http.Cookie, "Cookie2=([^;]*);*.*$", "\1" );
    }

hash_data(req.http.X-Varnish-Hashed-On);
return(hash);

On the compilation phase it works fine

but when I send a web request with these user cases ( first send with
cookie1 and then both cookie1 and cookie2) , it always returns the data
cached with cookie1 and does not respect the cookie2 combination.

Please do let me know if I am doing something wrong.  I could not find
anywhere how do put multiple cookies in place for hashing the data.
