What is a Content-Type Header?
The Content-Type representation header is used to indicate the original media type of the resource (prior to any content encoding applied for sending).
Why is it important?
- Browser Rendering: Browsers use this header to decide how to handle the file. Without it, the browser must guess (MIME sniffing), which can lead to security vulnerabilities or incorrect display.
- Character Encoding: Specifying
charset=utf-8ensures text is rendered with the correct characters, preventing strange symbols from appearing in place of accents or special characters. - Security: Serving files with incorrect content types can lead to cross-site scripting (XSS) attacks if an attacker uploads a script disguised as an image.
