How to request and url without expect the response

[eluser]Ryubr[/eluser]
Hello,

I have tried to find a solution on the boards, nothing so far. My question is, i have in my Model class one function to add some data to a database and at the end to do a get or post for an external url just to signal it "i did it", but i don't want to expect the answer bacause it could delay the response to the application on my side if the external url is too slow or off-line. Just like ajax, but in this case server side, i would like to send the request and go on without wait for it to finish.

Any ideias about how to do it?

Thanks in advance
