"Safe" is a Hypertext Transfer Protocol (HTTP) method that doesn't modify the server's state or resources. Safe HTTP methods allow access to information without accidentally modifying or deleting server data, making it a read-only operation. It also enables caches to save requests, improving loading speeds and performance.
All safe methods are idempotent, which means applying a safe method to a specific resource multiple times has the same effect as applying it once. GET, HEAD, OPTIONS, and TRACE are common safe methods.
For example, a web browser sends a GET request to the server when a user visits a webpage, asking for the page's HTML content. Because GET is a safe method, the server can return the requested data without changing or creating anything on its end.
