varnish cache configuration for multiple domain

[Nuno Fernandes]

Your request has a cookie so it gets pickup by the code:

    if (req.http.Authorization || req.http.Cookie) {
#        /* Not cacheable by default */
        return (pass);               <<<<-------- It returns here without 
setting the backend
   }

if (req.http.host == "site3.tieto.com") {

        #You will need the following line only if your backend has multiple 
virtual host names
        set req.http.host = "site3.tieto.com";
	set req.http.X-Orig-Host = req.http.host;
        set req.backend = site3;
        return (lookup);
}

if (req.http.host == "sitetwo.tieto.com") {

        #You will need the following line only if your backend has multiple 
virtual host names
        set req.http.host = "sitetwo.tieto.com";
	set req.http.X-Orig-Host = req.http.host;
        set req.backend = site2;
        return (lookup);
}
