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, [1] or a 16-bit value for cable modems. [2]

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.
