如何在squid 2.7中使用3.1特性“ignore-cc" [英] How to use in squid 2.7 the 3.1 feature "ignore-cc"

问题描述

有什么办法可以忽略客户端Cache-Control: max-age=0"并始终让squid返回陈旧内容?

There is any way to ignore client "Cache-Control: max-age=0" and always let squid to return stale content?

在 Squid 3.2 中使用ignore-cc"工作并且请求永远不会到达后端(仅在重新验证时)，总是过时但在 Squid 2.7 中工作正常，除非您发送 Cache-control: max-age=0 和 If-Modified-Since 标头.

In Squid 3.2 works using "ignore-cc" and the request never reaches backend (only while revalidating), always is stale but in Squid 2.7 works fine unless you send the Cache-control: max-age=0 and If-Modified-Since headers.

推荐答案

好吧，在尝试了所有替代方案之后，我修改了源代码以实现该功能.

Well, after trying all alternatives, I modified the source code to implement the feature.

我在 Squid-2.7-stable9 中更改了文件 src/refresh.c:282:

I changed in the Squid-2.7-stable9 the file src/refresh.c:282:

282:    if (request) {

为了

282:    if (request && FALSE) {

<小时>

他们在 3.X 中做了类似的事情来实现 ignoreCc:

---

They do something like that in the 3.X to implement ignoreCc:

269:    if (request && !request->flags.ignore_cc) {

按预期工作.
