Question

我拥有域 *。com的ImageResizing性能许可证该域指向Cloudfront CDN，然后指向负载均衡器，其下有服务器。因此，访问我们服务器的请求来自域* .us-east-1.elb.amazonaws.com，这使得许可证无效。有谁知道我们如何克服这个问题？

Answer 1

Is there a custom name? I.e, myinstance.us-east-1.elb.amazonaws.com? If so, this would be the domain you would register the license key under. ImageResizer can't know what domain name it's published under unless that name is transmitted to it via HTTP as part of the HOST header. (Or, another header, if the original domain is forwarded somehow - we could add a fallback path - if so, open an issue (or PR) on Github). You might consider a DRM-free license (Like Elite) to reduce the long-term hassle associated with changing load balancers and configurations. We don't suggest domain-restricted licenses for complex setups, particularly at a scale that requires load balancing. Also, keep in mind that it is 100% open-source (half AGPL 3, half Apache 2), and you're legally free to strip the DRM out and make your own builds, even under the commercial license terms. We really don't mind.
