Actually, warnings produced by -w can often be viewed in the raw data returned by the HTTP server. It won't display in the browser, but is visible with GET (or is it HEAD?)

Are you sure? I've just tried creating a script which causes an unitialized value warning. Whenever it's run as a CGI script it indeed spews said warning to the server error log. But I can't provoke the server into yielding the warning in any headers.

I've tried telnetting directly to port 80 on the server and using both HEAD and GET (though I'm fairly sure it would violate the HTTP spec for those two to return different sets of headers) and don't see any warnings.

What do they look like when you see them — what HTTP header do they use? I'm just getting Date:, Server:, Connection:, and Content-Type:, exactly the same as I do with warnings turned off.
