HTTP headers manipulation

HTTP headers manipulation involves the inspection, iteration, and modification of the metadata fields exchanged between a client and a server during an HTTP transaction.^[400-devops-09-scripting-language-golang-introduction-part-3http-readme.md]

Accessing Request Headers

In an HTTP server context, headers from the incoming request are typically accessed as a dictionary or map data structure^[400-devops-09-scripting-language-golang-introduction-part-3http-readme.md]. This allows the server to iterate through the key-value pairs to inspect information such as content type or user agent^[400-devops-09-scripting-language-golang-introduction-part-3http-readme.md].

Modifying Response Headers

Servers can also manipulate headers on the ResponseWriter object before sending the response body to the client^[400-devops-09-scripting-language-golang-introduction-part-3http-readme.md]. This is often done to add custom metadata or specific instructions to the client.^[400-devops-09-scripting-language-golang-introduction-part-3http-readme.md]
