Any idea why I might be getting these messages when using HttpClient?

at depth 0 - 18: self signed certificate  
could be a relative URI in location header which is not recommended  
‘The field value consists of a single absolute URI’ in HTTP spec

Thanks,  
T.

This seems to take care of the last two statements:

```
  # HACK to fix redirect bug/feature
  client.redirect_uri_callback = lambda do |uri, res|
    page = res.header['location'].first
    page =~ %r/http/ ? page : @uri + page
  end

```

I’m still baffled by the “certificate” message.

Because [https://rubyforge.org/](https://rubyforge.org/) uses a self signed certificate which  
means almost no security there. HTTPClient warns you about it.
