I'm sorry if this question has already been asked, but I haven't found any info either via search engines or the forum.

I have an app that has the frontend (ExtJS) on one domain and the webservices servicing the frontend on another domain.

Everytime I make a request to an URL, an OPTIONS request is sent to the server first. I understand this is something that could be wanted, but does anyone know (or can point me to the doc) on how to make ExtJS not do this OTIONS call ?

Thanks in advance for your help,
