I need to have a zero height iframe that changes its height and show
the content of a file if it does exist on the server.
I need to check every so often(a minute or so) the existance of the
file.
How can I do this ?
any example is highly appreciated
See below for an example approach. It's impossible to say whether
this will work for your situation without knowing more about it (ie.
Are the files yours? Can you edit them? If so, dynamic resizing may
be possible).
