yea I actually got that part right this time. This same function works fine if I change the POST stuff to GET, which is the way it is normally.

Ive just changed 
m.http.SetUrl(feed_url)

to
strx = ReadAsciiFile("tmp:/apfavorites")
		m.http.SetUrl(feed_url)
		m.http.AsyncPostFromString("AID=" + strx)

and 
xml=m.http.GetToString()

while true
    msg = Wait(8000, m.port )
    If msg = invalid Then
    print "Error: invalid"
    Else If Type( msg ) = "roUrlEvent" Then
    if msg.GetString()
    xml= msg.GetString()
    End If
    end if

it prints the error and crashes on the next block because the xml variable is empty

That's actually a much bigger change that it may look. You went from the synchronous GetToString() to the asynchronous AsycnPostFromString() method. The former doesn't require a port and wait loop, while the second does, so I'd bet it is an issue with the port you're listening on. Try just swapping:
xml = m.http.GetToString()
with:
xml = m.http.PostFromString("AID=" + strx)
and see if it works. That's swapping synchronous for synchronous...
