[TYPO3-german] external URL in a specific frame

[meta]

Hi folks,

i need to use a frameset to include external URLs in my website. So i 
got stuck with the following example...

1) I disable jumpURL with the following line of code

###
config.disablePageExternalUrl = 1
###

2) I now want to load the external URL that is declared in the 
Page-Header into a specific frame

###
2 = FRAME
2.obj = page
2.params = frameborder="0" marginheight="0" border="0" scrolling="AUTO"
2.src = field:url
###

How is it possible to access the external URL and set it as source of a 
frame?


Greetings
Andreas
