[Question] Uploading under same-site subdomain

[Denoder]

I'm trying to figure this out, but is it possible to upload under a subdomain but on the same site?

for instance in uploader.js if i make it like this:

    FileUpload.DEFAULTS = {
        url: 'https://subdomain.domain.com' + location.pathname,
        uploadHandler: null,
        sortHandler: null,
        uniqueId: null,
        extraData: {},
        paramName: 'file_data',
        fileTypes: null,
        maxFilesize: 256,
        template: null,
        isMulti: null,
        isPreview: null,
        isSortable: null,
        thumbnailWidth: 120,
        thumbnailHeight: 120
    }

I get this error:
AJAX handler 'onUpload' was not found.

This only happens when doing this under a different domain other than what the current domain is. If it's the same domain then it works fine.

Why tho?

@daftspunk Trying to utilize my own server's post upload limit while under cloudlfare. (don't want to grey-cloud the domain). The 100 mb limit is whack and the only solution right now would be to chuck, but i cant do parallel uploading while chunking, so i wanna use a subdomain of the same site that is grey-clouded while on the main domain that is orange clouded.
