Change Upload URL

I got it working for a small part.

In ckeditor.js I changed the encodeUriComponent to:

return u+(u.indexOf('/')!=-1?'/':'/')+w.join('/');

This will change the url to :

do_upload/CKEditor=summary/CKEditorFuncNum=2/langCode=en-gb

But how do I strip out:
[list=]CKEditor=
CKEditorFuncNum=
langCode=[/list]

I found the following:

getAction())return false;return true;};function p(u,v,w){var x=w.params||{};x.CKEditorFuncNum=u.name;x.CKEditorFuncNum=u._.filebrowserFn;if(!x.langCode)x.langCode=u.langCode;v.action=l

But if I remove a part like x.CKEditorFuncNum it will stop working.
Anyone who can support me with this?

Would appreciate it!

Thanks!

Got it!
