Http header on android : not sending

Hi All,

I have a htm site, ehat include js. By this reason i have to send username and pw to acces.
If i use : http://user:pw@domain.com
then it’s working by browser, simulator, ios device native app, android device browser BUT not working if i call the url from webpopup or webview - on android device.
It seems like android device not sending the html header???
Can anybody help?
Thank you.
