Nginx is a high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. It is known for its stability, rich feature set, simple configuration, and low resource consumption. Nginx is widely used to serve static content, handle high traffic loads, and act as a load balancer for web applications.
When dealing with web servers, you might encounter an error related to an 'Invalid Range' header. This issue typically manifests as a client-side error, where the server responds with a status code indicating that the range specified in the request is not satisfiable. This can lead to incomplete file downloads or failed media streaming.
The 'Invalid Range' error occurs when a client sends a request with a Range header that does not conform to HTTP standards. The Range header is used to request a specific part of a file, which is useful for resuming downloads or streaming media. If the specified range is invalid or exceeds the file's size, Nginx will return a 416 Range Not Satisfiable error.
To resolve the 'Invalid Range' issue, follow these steps:
Ensure that the Range header in the client request is correctly formatted. It should follow the syntax: Range: bytes=start-end. For example, Range: bytes=0-499 requests the first 500 bytes of the file.
Verify that the requested range does not exceed the size of the file being served. You can use commands like ls -lh or stat to check the file size on the server.
Ensure that your Nginx configuration allows for range requests. Check the nginx.conf file for the accept_ranges directive, which should be set to 'on'.
http {
...
server {
...
location / {
...
accept_ranges on;
}
}
}
After making changes, test your Nginx configuration with the command:
nginx -t
If the test is successful, reload Nginx to apply the changes:
nginx -s reload
For more information on handling range requests in Nginx, you can refer to the official Nginx documentation. Additionally, understanding HTTP headers can be enhanced by reviewing the MDN Web Docs on Range headers.
