Introduction
When you encounter the HTTP response status code 494 “Request Header Too Large,” it means that the server received an HTTP request with headers that are too large.
This can happen if the client sends too much data in the headers or if one or more headers are too long. The server cannot process such large headers, and it’s essential to ensure that the request headers are within acceptable limits for successful communication.
In Action
When you encounter the HTTP response status code 494 “Request Header Too Large,” it means that the server cannot process the HTTP request because the request itself is too large or one or more of the HTTP headers included in the request are too long.
This can happen when the client sends a lot of data in the headers, which exceeds the server’s capacity to handle. It’s essential to check the size of the headers and reduce them if needed to ensure successful communication with the server.
Note that the 494 status code is similar to the official 431 “Request Header Fields Too Large” status code, and in some cases, a 414 “URI Too Long” or 400 “Bad Request” code may be returned instead if the headers are too large for the server’s buffers.
Remember that search engines like Google will not index URLs with the 494 “Request header too large” response status, and any URLs that were previously indexed but are now returning this status code will be removed from the search results.
Conclusion
The 494 HTTP status code, “Request Header Too Large,” indicates that the server cannot process the client’s request because either the request itself is too large or one or more of the HTTP headers in the request are too long. To resolve this, the client should check the size of the headers and reduce them if necessary to ensure successful communication with the server.
