HSTS 检查
查看网站是否声明强制 HTTPS 及其有效时间。
技术术语
- HSTS
- Tells browsers to only ever connect over HTTPS, so visitors can't be downgraded to plain HTTP.
- HSTS max-age
- How long browsers remember to only use HTTPS. The HSTS preload list needs at least a year.
- includeSubDomains
- Applies HSTS to every subdomain too, so none of them can be reached over plain HTTP.
- HSTS Preload
- Asks browsers to build the site into their HTTPS-only list, protecting even the very first visit.
