よくある質問
What is a MIME type?+
MIME (Multipurpose Internet Mail Extensions) types identify the format of a file or data. They follow the format type/subtype (e.g., text/html, image/png, application/json). Servers send MIME types in Content-Type headers so browsers know how to handle the response.
Why does MIME type matter?+
If a server sends the wrong MIME type, browsers may refuse to process the file. For example, serving JavaScript as text/plain instead of application/javascript can block script execution. Incorrect MIME types also cause download dialogs instead of rendering.
