The HTTP 413 error occurs when the server informs the client that the size of the request being sent exceeds the allowed limit. This error may happen when you attempt to upload a large file or send a lot of data to the server.
In many cases, this limitation is determined by the server or an application that runs on the server. For example, on web servers like Apache or Nginx, there are parameters that usually determine the maximum size allowed for a single request.
To resolve this issue, you can adjust the server settings to allow larger data to be sent. However, in some cases, it is better to assess whether it is really necessary to send this size of data, as it may impact the server's performance.
If you do not have access to the server settings, you might need to reduce the amount of data being sent or contact the server administrator to increase the limit.
In most programming languages and development environments (such as PHP and Node.js), there are specific configurations and settings that can help manage this limitation.
Below are some examples of settings and codes related to this issue in the Nginx web server and PHP language:
server {
client_max_body_size 100M;
}
; In PHP
upload_max_filesize = 100M
post_max_size = 100M
Explanation of the Code Lines
Nginx Settings:
client_max_body_size 100M; - This line instructs the Nginx server to limit the maximum size of data sent to the client to 100 megabytes.PHP Settings:
upload_max_filesize = 100M - This line sets the maximum allowed size for uploaded files to 100 megabytes.post_max_size = 100M - This line sets the maximum allowed size for all data sent via the HTTP POST method to 100 megabytes.
