Hello friends! There is a situatuion like this for me: I am a PHP developer in a software company in India. I have used header function to call a third-party remote url passing it some query-string(e.g. http://xxx?abc=xyz&jkl=efg.)from a certain php page and the response is automatically coming back(i.e. it's a callback URL). Once I got response from the URL I need to generate auto-response for that.But the difficulty is that the page does not return back to original php page once redirected by header function. Can I call a remote URL with header function in a separate thread(process) without let to know the user of that page and giving him auto-response? Could someone guide me in this situatuion? Thank you! With regards Sandesh
