Node.js ajax call, does a data argument that's too long result in a "404 not found" error?

Question

Node.js ajax call, does a data argument that's too long result in a "404 not found" error?

I'm using an ajax request to send in ids and get information from my database to populate a table. Here's the client side:

userLookup: function (callBack, idList) {
    var data;
    data = { 'idList': idList};
    var url = "/idLookup";
    $.ajax({
        type: 'GET',
        url: url,
        data: data,
        dataType: 'json',
        success: function (data) {
            callBack(data);
        }
    });
}

And the server side starts like this:

module.exports = function (app) {
    app.get('/idLookup', function (req, res) {
    ....

The idList variable is a comma-seperated list of ids. When there are only 10 or so it works find, but when I get to about 50-100 I get a "404 - File not Found" error. Anyone know why this is, and how I can fix it?

I think there must be a limit on what you can pass into the 'data' parameter in a GET request. I did this and it works now.

userLookup: function (callBack, idList) {
    var data;
    //data = { 'idList': idList};
    var url = "/idLookup?idList=" + idList;
    $.ajax({
        type: 'GET',
        url: url,
        //data: data,
        dataType: 'json',
        success: function (data) {
            callBack(data);
        }
    });
}
