大家帮忙看下这段 Varnish 缓存规则是什么原因导致的语法错误

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

('input' Line 29 Pos 17)

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：

backend default {
.host = "127.0.0.1";
.port = "8080";
}

#revisit this list

remove req.http.Accept-Encoding;
} elsif (req.http.Accept-Encoding ~ "gzip") {
set req.http.Accept-Encoding = "gzip";
} elsif (req.http.Accept-Encoding ~ "deflate") {
set req.http.Accept-Encoding = "deflate";
} else {

}
