Reply to Mark Deazley You sir, you are my hero! This post is so useful, thanks! where can you see the version though? Thanx for sharing this infoAnd where the heck is the version? how to see the duration of persistant connection?? Daniel Villela 10 months agoThanksss, simple and practical Nam Nguyen H. 10 months agoDid API of every platform(Instagram, Discord, …) come from here? Thanks. It worked for this is very useful information, thanks for sharing this information with us. google extensions are very useful I also read an article on but the information which is mentioned in this article is not proper don’t go, do you know what does mean the double dots before parameter?

Header check sequence – Wikipedia
A header check sequence (HCS) is an error checking feature for various header data structures, such as in the Media Access Control (MAC) header of Ethernet. It may consist of a cyclic redundancy check (CRC) of the frame, obtained as the remainder of the division (modulo 2) by the generator polynomial multiplied by the content of the header excluding the HCS field.
The HCS can be one octet long, as in WiMAX,  or a 16-bit value for cable modems.

HTTP Header Check | HackerTarget.com
Review the HTTP Headers from a web server with this quick check.
Reviewing HTTP Headers
A great deal of information can be gathered in a check of the HTTP Headers from a web server. Server side software can be identified often down to the exact version running. Cookie strings, web application technologies, and other data can be gathered from the HTTP Header. This information can be used when troubleshooting or when planning an attack against the web server.
HTTP Header Check API
In addition to the web form above, we offer a second way to access the HTTP headers of any web site. Our HTTP Header API will trigger our system to get the headers and display them in a simple Text based output. Access the API using a web browser, curl, or any scripting language.
This query will display the HTTP headers from. Notice that if the web server sends a redirect 301 or a 302 the system will follow the redirect and display each set of HTTP Headers.
The API is simple to use and aims to be a quick reference tool. Like all our IP Tools there is a limit of 50 queries per day or you can Increase daily quote with a Full Membership.
List of Common HTTP Headers
By compiling all HTTP Headers from the top 1 million websites we have generated a list of the 100 most common HTTP Response Headers. Use this reference to quickly understand the use cases for the different HTTP headers.
Note that these are the response headers, meaning those found in the response from the HTTP server after a browser makes a request.
100 most Common HTTP Response Headers
Denotes the type of media
Date and Time from the response
Information about the Server Software
Assigns cookies from Server to Client
Controls network connection
Specifies compression type
Details how to determine if cache can be used rather than a new response from server
Details caching options in requests and responses
Encoding to be used for transfer of data
Specifies when the response becomes “stale”
Size of resource in number of bytes
Hosting and Backend Server Frameworks may use this. Can reveal sensitive information (version and software).
Serialising one or more links in HTTP headers
Related to caching, may be implemented in different ways.
Specifies how long a persistent connection stays open
Last modification date of resource. Used for caching.
Disables MIME Sniffing and forces browser to use type shown in Content-Type
CloudFlare Header. A hashed value encoding information about the data center and the request.
Cache Validation Tag. Also used for tracking users with cookies disabled.
Specifies whether browser should show page in an iFrame
CloudFlare header shows whether a resource is cached
Force communication to use HTTS (not HTTP)
Enables Cross Site Scripting (XSS) filtering
Reporting and enforcement of Certificate Transparency. Prevents the use of mis-issued certificates for the site. When enabled the Expect-CT header requests that Chrome checks certificates for the site appear in public CT logs.
Used by CDN’s to specify whether resource in CDN cache matches server resource
Time in seconds resource has been in proxy cache
One way to switch from HTTP to HTTPS
Describes the language(s) intended for the document
Privacy Protocol that was not widely adopted
Controls which resources the client can load for the page
Added by proxies. Can be used for both forward and reverse proxies (requests & responses)
List other ways to access service
Specifies the version of being used
Details whether the response can be shared.
Compatiability header for old versions of Microsoft Internet Explorer (IE) and Edge
Rules which referrer information sent in the referrer header is incorporated with requests
Header used for adding troubleshooting information??
An option for developers to set network error reporting.
Specific to IE8. Stops downloads opening directly in browser.
Enable caching in NGINX reverse proxy
Used for HTTP Cache validation and conditional requests using If-Match and If-None-Match
Unique request ID that associates HTTP requests between a client and a server.
Non-standard header related to caching, use can vary between different proxy & cdn networks
Data successfully located in cache memory
ID of the current request and the ID of the request that populated the Varnish cache
provides reason for a ‘MISS’ result in the x-cache
exposes information/meta data about the site such as version of software
Tags the clients about the cache-group to which they belong
Plesk Hosting Software
Shows the version of the framework
Exposes name and version of CMS
Contains the date/time after which the response object is considered stale
Amazon CloudFront ID (CloudFront requires this information for debugging. )
Indicates if request was served from Drupal Cache (Hit or Miss)
Internet explorer header compatibility filter for blocking XSS
Conveys information for the request-response cycle
Header specifying compression (gzip / compress / deflates etc)
A “Fastly” header: end to end request timing information
reveals time application takes to serve a request
Maybe same as “Host:” header?
info incl version on software used by server
Recruitment ‘ad’ by
Added when clouflare is used
HSTS informs browser to use HTTPS not HTTP
Identifies object (and version) for caching purposes
Allows you to choose content search engines can crawl on the site
Wix hosting request ID
Module for apache (and nginx) to increase performance
Non-standard HTTP response status (Status: 200 OK)
Non-standard caching related
Specifies requests and responses caching mechanisms
Cache Enabled (True / False)
Exposes server side software
Sites use this to bypass ad blocker plugins
Non-standard host header
Nginx Caching Header
In the above table there are a significant number of HTTP Headers that have “X-” apppended to the header. This denotes the header is non-standard. It is not a part of the HTTP standard but is often used by web servers, web applications, and caching systems to pass information between the server / application and the browser.
