Thank you everybody for your responses!

According to w3c XMLHttpRequest class does not support "OPTIONS *" request.
Most likely it will not be supported soon.
Please see mailing list thread by using the following link for more
details:

Do you mind to leave "OPTIONS *" request behind until it is available in
w3c specification?

There is one more thing. Should we care about cross-origin resource sharing
protocol? If I got it right, XMLHttpeRequset should perform "OPTIONS"
preflight request before real cors request. Please see links below for more
details:
http://www.w3.org/TR/cors/#cross-origin-request-with-preflight-0
Does it make sense to have separate method for "OPTIONS" request in
QNetworkAccessManager if it is the case (like for get or post)?
