7. Comments

	1. General Results, most used to calculate the result
A	name "nih.gov" is domain, public suffix is ".gov", top-level-domain is ".gov", top-level-domain-type is "sponsored", tld-manager is "General Services Administration Attn: QTDC, 2E08 (.gov Domain Registration)", num .gov-domains preloaded: 5117 (complete: 270180)
A	Good: All ip addresses are public addresses
	Warning: Only one ip address found: nih.gov has only one ip address.
	Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: nih.gov has no ipv6 address.
A	Good: No asked Authoritative Name Server had a timeout
A	Good: destination is https
A	Good - only one version with Http-Status 200
A	Good: one preferred version: www is preferred
A	Good: No cookie sent via http.
	HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
A	Good: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
A	http://www.nih.gov/ 95.100.248.194	301	https://www.nih.gov/	Correct redirect http - https with the same domain name
A	http://www.nih.gov/ 95.100.248.211	301	https://www.nih.gov/	Correct redirect http - https with the same domain name
I	https://www.nih.gov/ 95.100.248.194	200		Content problems or problems with resources included - http links, files doesn't exist, different Content-Type definitions. Check the Html-Content - Part.
I	https://www.nih.gov/ 95.100.248.211	200		Content problems or problems with resources included - http links, files doesn't exist, different Content-Type definitions. Check the Html-Content - Part.
I	https://www.nih.gov/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de	404		Content problems or problems with resources included - http links, files doesn't exist, different Content-Type definitions. Check the Html-Content - Part.
N	https://156.40.212.210/ 156.40.212.210	302	https://maintenance.cit.nih.gov/	Error - Certificate isn't trusted, RemoteCertificateNameMismatch
	Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain nih.gov, 1 ip addresses, 1 different http results.
B	No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.nih.gov

B				Info: Header-Element is deprecated. report-uri /report-csp-violation
A				Good: default-src directive only with 'none' or 'self', additional sources are blocked.
A				Good: default-src without 'unsafe-inline' or 'unsave-eval'.
E				Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
A				Good: frame-ancestors directive found. That limits pages who are allowed to use this page in a frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
E				Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
A				Good: No object-src found, but the default-src used as fallback is defined and restricted.
F				Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce.
A				Good: script-src without * and a scheme found.
A				Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
A				Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.
A		X-Content-Type-Options		Ok: Header without syntax errors found: nosniff
A		X-Frame-Options		Ok: Header without syntax errors found: SAMEORIGIN
B				Info: Header is deprecated. May not longer work in modern browsers. SAMEORIGIN. Better solution: Use a Content-Security-Policy Header with a frame-ancestors directive. DENY - use 'none', SAMEORIGIN - use 'self'. If you want to allow some domains to frame your page, add these urls.

E				Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
A				Good: No object-src found, but the default-src used as fallback is defined and restricted.
F				Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce.
A				Good: script-src without * and a scheme found.
A				Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
A				Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.

	4. Content- and Performance-critical Checks
	http://nih.gov/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 156.40.212.210	-110		Fatal: Check of /.well-known/acme-challenge/random-filename is blocked, http connection error. Creating a Letsencrypt certificate via http-01 challenge can't work. You need a running webserver (http) and an open port 80. If it's a home server + ipv4, perhaps a correct port forwarding port 80 extern ⇒ working port intern is required. Port 80 / http can redirect to another domain port 80 or port 443, but not other ports. If it's a home server, perhaps your ISP blocks port 80. Then you may use the dns-01 challenge. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
A	Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
	https://www.nih.gov/ 95.100.248.194	200		Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.

	https://www.nih.gov/ 95.100.248.194	200		Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
	https://www.nih.gov/ 95.100.248.211	200		Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
A	Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
A	Good: Some script Elements (type text/javascript) with a src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
	https://www.nih.gov/ 95.100.248.194	200		Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 10 script elements without defer/async.

	https://www.nih.gov/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de	404		Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage.

All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 9 script elements without defer/async.
A	Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 47 external CSS / JavaScript files found
A	Good: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 33 images (type image/png, image/jpg, image/jpeg, image/webp, image/gif) found without additional Compression. Not required because these images are already compressed
	Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 46 with Cache-Control max-age too short (minimum 7 days), 12 with Cache-Control long enough, 58 complete.
A	Good: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 33 image files with long Cache-Control max-age found
A	Good: All checked attribute values are enclosed in quotation marks (" or ').
A	Good: All img-elements have a valid alt-attribute.: 33 img-elements found.
A	Good: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
