I'm using res = getApi().blockAndCallUrl(...) in an ActionScript login event handler. When res.getDataAsString() is executed, the string is a somewhat mangled version of what is sent across the wire. URL is a normal "http://" one, data is fine in other situations, method is GET.
What happens looks like a buffer overwrite error: parts of the string are repeated towards the end.
Is there a limit to the length of the content? What I'm reading is never bigger than a few K in size.
