首先說(shuō)明一下，使用虛擬機(jī)安裝centos 6 64位
Varnish版本3.0.0/3.0.2 Nginx版本1.0.6
Varnish：172.2.2.108
Nginx：172.2.2.109
本地PC hosts文件中已經(jīng)設(shè)置：
172.2.2.108 www.t1.com（通過(guò)varnish訪問(wèn)）
172.2.2.109 www.t2.com（通過(guò)nginx訪問(wèn)）
varnish啟動(dòng)后，通過(guò)nginx訪問(wèn)
在瀏覽器中輸入www.t2.com，可正常訪問(wèn)
通過(guò)varnish訪問(wèn)時(shí)：
在瀏覽器中輸入www.t1.com，會(huì)出現(xiàn)問(wèn)題，問(wèn)題是：第一次訪問(wèn)的時(shí)一直在load，始終打不開一直load，如果點(diǎn)下刷新就立刻顯示頁(yè)面，但是當(dāng)你再次訪問(wèn)的時(shí)候又出現(xiàn)第一次打開時(shí)的情況，再一刷新立刻又可以了！
各位大神都遇到過(guò)這個(gè)問(wèn)題嗎？換了2.0.x的版本任然有這個(gè)問(wèn)題
下面是我的vcl配置：
backend t1 {
.host = "172.2.2.109";

# redefine any of these subroutines, the built-in logic will be
# appended to your code.
