简而言之,我正在尝试
请注意,当某人在地址栏中输入URL并按下回车键时,Chrome默认将Cache-Control设置为最大年龄(max-age)= 0。 Cookie是通过session_start设置的默认php cookie和自定义会话cookie。
目前我想忽略Cookie和Cache-Control头。
以下是我的VCL设置:
响应头是:
if (beresp.ttl < 120s) {
set beresp.ttl = 120s;
unset beresp.http.Cache-Control;
}
我在我的VCL配置文件中,但它没有起作用。以下是更详细的信息:
这是我的请求头:

以下是我的VCL设置:
sub vcl_recv {
# Happens before we check if we have this in cache already.
#
# Typically you clean up the request here, removing cookies you don't need,
# rewriting the request, etc.
}
sub vcl_backend_response {
# Happens after we have read the response headers from the backend.
#
# Here you clean the response headers, removing silly Set-Cookie headers
# and other mistakes your backend does.
# set beresp.ttl = 60s;
if (beresp.ttl < 120s) {
set beresp.ttl = 120s;
unset beresp.http.Cache-Control;
}
}
sub vcl_deliver {
# Happens when we have all the pieces we need, and are about to send the
# response to the client.
#
# You can do accounting or modifying the final object here.
if (obj.hits > 0) {
set resp.http.X-Cache = "HIT";
} else {
set resp.http.X-Cache = "MISS";
}
}
响应头是:
Accept-Ranges:bytes
Age:0
Connection:keep-alive
Content-Length:24
Content-Type:text/html

这是一个失误。
后端服务器上的PHP基本上只会输出一个随机数:
<?php
echo 'Hello worlds';
echo '<hr/>';
echo rand();
?>
