@@ -201,6 +201,10 @@ To customize other PHP limits you can simply change the following variables:
 - `PHP_MEMORY_LIMIT` (default `512M`) This sets the maximum amount of memory in bytes that a script is allowed to allocate. This is meant to help prevent poorly written scripts from eating up all available memory but it can prevent normal operation if set too tight.
 - `PHP_UPLOAD_LIMIT` (default `512M`) This sets the upload limit (`post_max_size` and `upload_max_filesize`) for big files. Note that you may have to change other limits depending on your client, webserver or operating system. Check the [Nextcloud documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/big_file_upload_configuration.html) for more information.
 
+To customize Apache max file upload limit you can change the following variable:
+- `APACHE_BODY_LIMIT` (default `1073741824` [1GiB]) This restricts the total 
+size of the HTTP request body sent from the client. It specifies the number of _bytes_ that are allowed in a request body. A value of **0** means **unlimited**. Check the [Nextcloud documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/big_file_upload_configuration.html#apache) for more information.
