The write-up on LWP::Simple::get says:

You will not be able to examine the response code or response headers (like 'Content-Type') when you are accessing the web using this function. If you need that information you should use the full OO interface (see LWP::UserAgent).

So if I was you, I'd follow that suggestion.
