NCBI 도메인에 https를 적용하면서, PubMed Linkout file에서도 https를 사용할 것을 권고하였습니다. 아래 내용은 메일 전문입니다.
NCBI completed the implementation of https across the entire domain. We need to inform you that, as a result of this change to https, referrer information may be dropped when links are directed from PubMed to your Web site using http. This means that it is likely that you may not be able to accurately track usage directed to your site from the NCBI domain.
If your Web site has implemented https, please change the information you provide in your LinkOut files to use https and to update your scripts to use https when generating new LinkOut files.
We will soon update all LinkOut files currently using the http://dx.doi.org to https://dx.doi.org. We will make the change for you either later this week or early next week. However, please be sure to update your scripts to use https when generating new LinkOut files.
