试了下Varnish官方给出的一个缓存应用实例，结果得到了下面这个错误：
Message from VCC-compiler:

Syntax error at

if (req.url ~ "\ (utm_ (campaign |? medium | source | term) | adParams | client | cx | eid | fbid | feed | ref (id | src) |? v (er | iew)) =" ) {

---------------- # --------------------------------- -------------------------------------------------- -------------------

Running VCC-compiler failed, exit 1

这个错在哪呢？

全部缓存规则如下：
