However, in cases where the cached resource is confidential, caching can lead to vulnerabilities - and must be avoided.

Disabling Caching Of Confidential ResourcesĬaching is a valuable and effective technique for optimizing performance in client-server architectures, and HTTP, which leverages caching extensively, is no exception. HTTP headers provide a flexible and extensible mechanism that enables the rich and varying use cases found on the web today. Today, hundreds of headers are used by web apps, some standardized by the Internet Engineering Task Force (IETF), the open organization that is behind many of the standards that power the web as we know it today, and some proprietary. Plain-text HTTP response headers can be examined easily using cURL, with the –head option, like so: $ curl -head Ĭontent-Type: text/html charset=ISO-8859-1 They are designed to enable both the HTTP client and server to send and receive meta data about the connection to be established, the resource being requested, as well as the returned resource itself. Technically, HTTP headers are simply fields, encoded in clear text, that are part of the HTTP request and response message header.

While the code examples are for Node.js, setting HTTP response headers is supported across all major server-side-rendering platforms and is typically simple to set up. In this article, we’ll show how web developers can use HTTP headers to build secure apps. HTTP response headers can be leveraged to tighten up the security of web apps, typically just by adding a few lines of code. Indeed, these days, understanding cyber-security is not a luxury but rather a necessity for web developers, especially for developers who build consumer-facing applications. In 2016, approximately 40% of data breaches originated from attacks on web apps - the leading attack pattern. Web applications, be they thin websites or thick single-page apps, are notorious targets for cyber-attacks.
