The headers are entirely encrypted. The only information going over the network 'in the clear' is related to the SSL
Transport Layer Security
Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both of which are frequently referred to as 'SSL', are cryptographic protocols designed to provide communications security over a computer network. Several versions of the protocols are in widespread use in applications such as web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP).
What are HTTP security headers?
What are HTTP Security Headers? HTTP security headers are a subset of HTTP headers and are exchanged between a web client (usually a browser) and a server to specify the security-related details of HTTP communication. Some HTTP headers that are indirectly related to privacy and security can also be considered HTTP security headers.
What is the difference between HTTP headers and proprietary headers?
HTTP headers let the client and the server pass additional information with an HTTP request or response. An HTTP header consists of its case-insensitive name followed by a colon (: ), then by its value. Whitespace before the value is ignored. Custom proprietary headers have historically been used with an X- prefix,...
Why is it important to set up security headers correctly?

Can HTTP headers be hacked?
HTTP Host header attacks exploit vulnerable websites that handle the value of the Host header in an unsafe way. If the server implicitly trusts the Host header, and fails to validate or escape it properly, an attacker may be able to use this input to inject harmful payloads that manipulate server-side behavior.
Are HTTP headers encrypted in SSL?
HTTPS encrypts all message contents, including the HTTP headers and the request/response data.
What is HTTP header security?
HTTP security headers are a fundamental part of website security. Upon implementation, they protect you against the types of attacks that your site is most likely to come across. These headers protect against XSS, code injection, clickjacking, etc.
Can headers be sniffed?
The entire HTTP request (and response) is encrypted, including the URL. But yes, there is a way an attacker could grab the full URL: through the Referer header. If there is any external file (Javscript, CSS, etc.) which is not over HTTPS, the full URL could be sniffed in the Referer header.
Why is HTTP not secure?
Why HTTPS? The problem is that HTTP data is not encrypted, so it can be intercepted by third parties to gather data passed between the two systems. This can be addressed by using a secure version called HTTPS, where the S stands for Secure.
What HTTPS Cannot Encrypt?
What information does HTTPS not protect? While HTTPS encrypts the entire HTTP request and response, the DNS resolution and connection setup can reveal other information, such as the full domain or subdomain and the originating IP address, as shown above.
Are request headers case sensitive?
Are http headers case-insensitive? The http header names are case-insensitive. So “Content-Type” is equivalent with “content-type”.
Why do we use headers in API?
HTTP Headers are an important part of the API request and response as they represent the meta-data associated with the API request and response. Headers carry information for: Request and Response Body. Request Authorization.
How do I know if my HTTP security header is not detected?
This QID is reported when the following HTTP headers are missing X-Frame-Options, X-XSS-Protections HTTPand the X-Content-Type-Options. Please make a request for the starting URI in your web application and check its response headers are using a proxy. One or more of the above headers must be missing in the response.
Are headers encrypted?
Yes, headers are encrypted. It's written here. Everything in the HTTPS message is encrypted, including the headers, and the request/response load. Wikipedia is not the spec, which is what you should be quoting.
Does HTTP headers support authentication?
HTTP supports the use of several authentication mechanisms to control access to pages and other resources. These mechanisms are all based around the use of the 401 status code and the WWW-Authenticate response header. The client sends the user name and password as unencrypted base64 encoded text.
Are TCP headers encrypted?
The TCP header and payload are encrypted by TLS. Because encryption is performed in the protocol on one end system and decryption in the protocol of the other end system, the packet payload remains encrypted along the entire path.
Are rest headers encrypted?
Are the headers encrypted? Yes, if you are using the HTTPS (HTTP over SSL) protocol instead of plain HTTP.
How are HTTP headers encoded?
HTTP messages are encoded with ISO-8859-1 (which can be nominally considered as an enhanced ASCII version, containing umlauts, diacritic and other characters of West European languages). At the same time, the message body can use another encoding assigned in "Content-Type" header.
Are REST requests encrypted?
Since REST APIs use HTTP, encryption can be achieved by using the Transport Layer Security (TLS) protocol or its previous iteration, the Secure Sockets Layer (SSL) protocol. These protocols supply the S in “HTTPS” (“S” meaning “secure'') and are the standard for encrypting web pages and REST API communications.
Does TLS encrypt TCP header?
The TCP header and payload are encrypted by TLS. Because encryption is performed in the protocol on one end system and decryption in the protocol of the other end system, the packet payload remains encrypted along the entire path.
With HTTPS, are the URL and the request headers protected as the ...
That Depends.. If you use a packet sniffer you cannot see the data sent over the wire. The main problem with this approach is that the request url is often saved in the server's log in plain text, the browser history keeps the url, URLs are passed in Referrer headers and maybe persisted by third party services (google analytics).

Summary. The use of TLS, and Enforced TLS in a lot of cases now, is becoming more and more common. Cyber criminals are continually trying to intercept and read other people's emails with malicious intent.
Why does SSL on Vhosts not work?
That's why SSL on vhosts doesn't work too well - you need a dedicated IP address because the Host header is encrypted. † The Server Name Identification (SNI) standard means that the hostname may not be encrypted if you're using TLS. Also, whether you're using SNI or not, the TCP and IP headers are never encrypted.
What level of encryption is SSL?

And, malware at either end can take snapshots of data entering (or exiting) the SSL protocol - such as (bad) Javascript inside a page inside HTTPS which can surreptitiously make http (or https) calls to logging websites (since access to local harddrive is often restricted and not useful).
Is a URL secure?
Also, the URL isn't always secure: the domain, protocol, and port are visible - otherwise routers don't know where to send your requests. Also, if you've got an HTTP proxy, the proxy server knows the address, usually they don't know the full querystring. So if the data is moving, it's generally protected.

Does a wildcard detect a security policy?
This tool only detects the presence of a security policy in the header response. It doesn't validate any policies for best practices. Therefore, even if you have a 'Content Security Policy' with a wildcard, it will still pass as having detected a valid 'Content Security Policy'.
Can analytics use https?
For example, analytics can introduce 5 different external URLs on your site which you can't easily see in the source code. It's still possible to introduce a very rudimentary 'Content Security Policy' by using the below code which simply enforces that all external URLs use the https protocol.
What is referer header?
The Referer (sic) header contains the address of a request ( for example, the address of the previous web page from which a link to the currently requested page was followed, or the address of a page loading an image or other resource). This has many fairly innocent uses, including analytics, logging, or optimized caching. However, there are more problematic uses such as tracking or stealing information, or even just side effects such as inadvertently leaking sensitive information.
What is referrer policy?
The Referrer-Policy header on your server to control what information is sent through the Referer header. For example, a directive of no-referrer would omit the Referer header entirely.
Can an image from a third party site be leaked?
By the same logic, an image from a third party site embedded in your page could result in sensitive information being leaked to the third party. Even if security is not compromised, the information may not be something the user wants shared.
Does HTTPS transmit referrer information?
This has many security advantages, including the fact that HTTPS sites will never transmit referrer information to non-HTTPS sites. This advice is less relevant now that most of the web is using HTTPS, but it is still a worthy consideration.
