Post Vars To Page In New Window

Hi all
I am just trying to send some variables from flash to an asp page.
Using the below method the variables are sent to the page.

sendText.loadVariables(“http://archive.mysite.com/livefeed/pages/login.asp”, “POST”);

My issue is that I want the page to open in a new window and then have the post method send the vars.

Presently it does not open a new window.

any suggestions out there???

cheers in advance
