[英]MVC4 Bundling Cache Headers
I want to change the cache headers sent from a bundle request. 我想更改从捆绑请求发送的缓存标头。 Currently it is varying by
User-Agent
but I don't want it to, is there a way to change the headers sent by a bundle request? 目前它是由
User-Agent
改变但我不希望它,有没有办法更改捆绑请求发送的标头?
After a quick look in the System.Web.Optimization
assembly I can see the headers get set in Bundle.SetHeaders
which is a private static function so I don't think its possible although I would love to be proven wrong. 在快速查看
System.Web.Optimization
程序集后,我可以看到标题在Bundle.SetHeaders
中设置,这是一个私有静态函数,所以我不认为它可能,尽管我希望被证明是错误的。
This isn't something that we currently expose today. 这不是我们目前公开的内容。 We only expose the Cacheability property on the BundleResponse that a IBundleTransform could change.
我们只在BundleResponse上暴露了IBundleTransform可能改变的Cacheability属性。 And yes we explicitly set the following things:
是的,我们明确地设置了以下内容:
HttpCachePolicyBase cachePolicy = context.HttpContext.Response.Cache;
cachePolicy.SetCacheability(bundleResponse.Cacheability);
cachePolicy.SetOmitVaryStar(true);
cachePolicy.SetExpires(DateTime.Now.AddYears(1));
cachePolicy.SetValidUntilExpires(true);
cachePolicy.SetLastModified(DateTime.Now);
cachePolicy.VaryByHeaders["User-Agent"] = true;
We have a work item our backlog to open this up and make this more extensible/customizable in the future. 我们有一个工作项目我们的积压工具打开它,并使其在未来更具可扩展性/可定制性。
There is a workaround around it as mentioned in janv8000's comment on this response . 正如janv8000对此响应的评论中提到的那样,有一个解决方法。 You need to add the following URL rewrite rule to your web server:
您需要将以下URL重写规则添加到Web服务器:
<system.webServer>
<rewrite>
<outboundRules>
<rule name="Cache Bundles" preCondition="IsBundles" patternSyntax="ExactMatch">
<match serverVariable="RESPONSE_Vary" pattern="User-Agent" />
<action type="Rewrite" value="Accept-Encoding" />
</rule>
<preConditions>
<preCondition name="IsBundles" patternSyntax="Wildcard">
<add input="{URL}" pattern="*/bundles/*" />
</preCondition>
</preConditions>
</outboundRules>
</rewrite>
</system.webServer>
Obviously you need to pay attention to have all your bundles in your bundles folder or change the IsBundles
precondition accordingly. 显然,您需要注意将所有捆绑包放在捆绑包文件夹中或相应地更改
IsBundles
前提条件。
