HTTP status: 5 Sub-resource URL
A non-standard but widely accepted header introduced originally by Microsoft to disable "content sniffing" or heuristic content type discovery in absence or mismatch of a proper HTTP
Content-Type declaration, which led to a number of web attacks. In general, presence of the header with its only defined value of
nosniff is considered as part of a properly secured HTTP response.
Fuzzy content type guessing is disabled+1
Controls the behavior of search engine bots and may contain most of the directives usually found in robots.txt file.Read more...
XmlHttpRequest from a website that is not in the same origin, which is a precaution against various types of data stealing attacks. The target server has to explicitly allow the origin domain using the
Access-Control-Allow-Origin (ACAO) header, or it may allow all origins to access it using a wildcard
*. The latter however creates a potential security issue if the website in question is transactional and processing sensitive data, so the wildcard should be only used on websites consciously offering public APIs.
The header sets permissive AJAX access by using wildcard origin
*. It may be OK if the website is a publicly accessible REST API but otherwise it should be not present at all

Expect-CT: max-age=604800, report-uri="https://report-uri.cloudflare.com/cdn-cgi/beacon/expect-ct"
The Expect-CT header allows sites to opt in to reporting and/or enforcement of Certificate Transparency requirements, which prevents the use of misissued certificates for that site from going unnoticed. When a site enables the Expect-CT header, they are requesting that the browser check that any certificate for that site appears in public CT logs.Read more...
The header defines a generic reporting framework which allows web developers to associate a set of named reporting endpoints with an origin. Various platform features (like Content Security Policy, Network Error Reporting, and others) may use these endpoints to deliver feature-specific reports in a consistent manner.Read more...
Network Error Logging (NEL) defines a mechanism enabling web applications to declare a reporting policy that can be used by an user agent to report network errors for a given origin.Read more...
