HTTP 414 URI Too Long — What It Means & How to Fix It

Error4xx client error

Overview

The HTTP 414 URI Too Long status code indicates the request URL is longer than the server is willing to process.

Key Details

  • Most servers and browsers have a maximum URL length, typically around 2,000-8,000 characters.
  • Previously known as "Request-URI Too Long."
  • This can occur when query string parameters are too numerous or too long.
  • Converting GET requests with many parameters to POST with a body can resolve this.

Common Causes

  • Too many query string parameters in the URL.
  • A redirect loop is appending parameters with each redirect.
  • Passing large amounts of data in the URL instead of the request body.
  • Encoded data in the URL inflating its length.

Steps

  1. 1Move large data from query parameters to the request body using POST.
  2. 2Reduce the number of query parameters.
  3. 3Check for redirect loops that may be appending parameters.
  4. 4If you control the server, increase the maximum URI length configuration.
