Codeigniter - 403通过Ajax发送包含3000个条目的数组时禁止访问

Question

I have a Controller which consumes Ajax requests and responds with the result of the database operation. The Ajax call is formed with a set of IDs (an array of ints) and a message.

When the set of IDs have a normal ammount of IDs (I tested with 20 IDs), the Ajax call returns normally. When trying to send 3000 IDs, I get an almost instant response with a 403 Forbidden Access error.

This is probably a Codeigniter or Apache server error. I looked for it, but didn't find any answer.

Thanks in advance.

On your AJAX code, are you sending it via GET?, if so, change it to POST

$.ajax({
        type: "POST",
        url: 'url',
        data: data,
        dataType: "json",
        cache: false,
        contentType: false,
        processData: false,
        success: function (data) {
            //some code
        }
    });
