【问题描述】：
我有一个简单的 jmeter 计划，使用 Uniform Random Timer:
Random Delay Maximum (in milliseconds): 15000.0
Constant Delay Offset (in milliseconds): 5000
我正在使用的 HTTP 标头数据：
Content-Type application/x-www-form-urlencoded
Accept-Language lt,en-us;q=0.7,en;q=0.3
Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
User-Agent Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0
Referer http://.../.../tao/Main/login
Accept-Encoding gzip, deflate
请求数据：
POST http://.../.../tao/Main/login
POST data:
loginForm_sent=1&login=u509&password=demo&processUri=&activityUri=&connect=Log+in
Cookie Data:
tao_XK0R3qTp=uijd30hi0gls2i9l2i2ikr97b3
Request Headers:

Content-Type: application/x-www-form-urlencoded
Accept-Language: lt,en-us;q=0.7,en;q=0.3

Referer: http://.../.../tao/Main/login
Accept-Encoding: gzip, deflate
Content-Length: 81
Host: ...
当我不使用随机计时器时，这是可行的。但是当我使用随机计时器时，这个 HTTP 请求不起作用。

清漆配置： 我还没有改变任何东西，所以配置是默认的：
backend default {
.host = "127.0.0.1";
.port = "8080";
}
从这里我可以假设由于某种原因apache服务器没有收到这个请求，或者超时了？ 所以结束我的问题：当我使用 Varnish 并且 jmeter 有随机计时器时，这个 HTTP 请求不起作用。当我删除随机计时器时，清漆没有问题。现在，当我不使用清漆时，无论是否使用随机计时器，它都可以使用。我想这更像是对想法/帮助的请求而不是问题。我似乎无法解决这个问题。
