opening a new window using the Header("Location:") function

Hi, I use the following code to redirect users to my custom error pages when submitting a form Header("Location: ". $form["missing_fields_redirect"]); When the code executes, it simply redirects to the URL specified in $form["missing_fields_redirect"] but stays within the same browser window. My question is: can I have the redirect page open in a new browser window (similar to target="_blank") when using the above code? Thanks, Don
