414 URI Too Long Error
What This Error Means
The 414 URI Too Long error indicates that the URL requested by the client is longer than the server is willing to interpret. This prevents buffer overflow attacks and other exploits.
Common Causes
- A redirect loop that keeps appending parameters to the URL.
- A client trying to pass too much data via GET parameters instead of POST.
- Malicious attempts to exploit the server.
- Broken links with excessive query strings.
How to Fix It (For Users)
- 1 Check the URL for an endless string of characters.
- 2 Clear your cookies and cache.
- 3 Contact the site owner if a link is broken.
For Site Owners / Developers
- Increase the `large_client_header_buffers` in Nginx or `LimitRequestLine` in Apache if you legitimately need long URLs.
- Switch from GET to POST requests for sending large amounts of data.
- Fix any redirect loops in your application.
