Preflighted Resquest and ExtJS

[uncle_costa]

Hi,

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,
Costa.

I don't believe ExtJS has any control over this, it's done behind the scenes by the browser.

See:

The second article suggests that you may be able to prevent the OPTIONS request by setting a suitable Content-Type header on the request. There are several ways to do this in ExtJS, see the docs for Ext.Ajax:
