ps. below is my changed VCL config file:

backend default {

sub vcl_recv {    if (req.request == "GET" && req.http.cookie) {

insert;    }}sub vcl_fetch {    if (obj.ttl < 120s) {        set obj.ttl = 
120s;    }}sub vcl_fetch {    remove obj.http.Set-Cookie;}sub vcl_recv { if 
(req.request == "GET" && req.url ~ "\.(gif|jpg|swf|css|js).*") {    lookup; }}
