FOLLOWLOCATION does not work with some php configurations

[oscarotero]

After an issue reported by @mwallisch seems like curl does not follow the redirect responses under some configurations related with safe_mode and open_basedir.

Hey Oscar, thanks for your quick response and for creating this issue here.

I have absolutely no insight into curl, and I am still new to this library, so I am not sure what my debug-findings mean.

However, within Embed\RequestResolvers\Curl I replaced ] + $this->config); on Line 138 with ]); So essentially I tested how it would behave with $this->config set to an empty Array. And voila Curl followed the redirect and everything worked. So this issue seems to be about some curl OPTION confusion. Again, I don't really know much about it. But hopefully this gets someone with more insight started.

mmm, interesting.

This means some of the configuration values in https://github.com/oscarotero/Embed/blob/master/src/RequestResolvers/Curl.php#L17 makes this to fail.

After remove the CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST default options, seems to work fine. I have to ensure this does not causes collateral damage.

After some tests, I wasn't able to make this work in all environments. In some servers CURLOPT_SSL_VERIFYHOST must be disabled and in others enabled. So I leave the things as they were before.
But now the exception contains more information so if you see an error related with SSL, maybe changing this settings fixes the problem.
