What is an HTTP Header?

HTTP Headers are packets of metadata attached to HTTP requests and responses. While some of the information they provide is merely supplemental, headers also contain pertinent information about a user’s authorization, about the user’s preferences, and about the format of the encoded data.

HTTP headers consist of a case-insensitive name followed by a colon, then by its value, with a single line break between pairs. Commonly used headers include Content-Type, which indicates the media type of the resource, Authorization, employed for authorization purposes, and Cookie, a bundle of stored preferences and session data.

Within the context of browser automation, header management is integral to ensuring the proper functioning of your scripts. Depending on the sophistication of your target web pages, it may take some research to understand exactly what headers will ensure you can access the right data, in the right region, without being blocked. Modern automation libraries like Playwright and Puppeteer simplify header management considerably. And BrowserCat supports both!
