HTTP 414 URI Too Long

What is HTTP 414 URI Too Long?

The 414 (URI Too Long) status code indicates that the target URI is longer than the server is willing to interpret. This is often caused by excessive query string parameters or deeply nested URL paths. Most servers have a configurable URI length limit.

Common Use Cases

• Excessive query string parameters
• Long URL-encoded data in GET requests
• Infinite redirect loops causing URL growth
