Question

Are any CDNs (Content Delivery Networks) that provide control and/or customization of all or most HTTP headers?

具体来说,我很想控制胎盘、ETag和Cache-Control头脑,尽管其他头脑也关心我。

我的理解是,CDNs的一部分是“公正工作”,使这些头盔达到某种最佳价值(大多数使用情况),但我肯定有兴趣控制这些头盔。

Akamai has a full interface for allowing this type of control on a per-property, per-header basis. It is a standard XML based config file. You can set each header to be a specific value, respect the headers passed through, add if not present, have exceptions based on User Agent etc.

从根本上说,它完全可以想象。我发现,在缺席时会出现违约情况,但允许申请/行政确定自己的价值通常是最佳办法,但实际上取决于开发商/行政的质量和理解。

Like most CDN providers Akamai have some default behaviors baked in, but the values are completely configurable. It has been a couple of years since I actively managed a CDN, but at the time Limelight was working on being feature compatible with Akamai and was most of the way there, so I would expect that they have similar functionality now.

总的来说,大多数CDN供应商将努力与市场中的主要参与者保持特征兼容,Akamai公司对CDN公司来说是肯定的。
