Hi,

after debugging some OCSP responses, I realized OCSP servers such as
ocsp2.globalsign.com (e.g. http://ocsp2.globalsign.com/gsalphasha2g2 for
AlphaSSL) which uses cloudflare, are denying queries from openssl

My post, e.g:
POST /gsalphasha2g2 HTTP/1.0
Content-Type: application/ocsp-request
Content-Length: 122
{data}

receives a 403 forbidden from the cloudflare-nginx, with the informative
message that "Direct IP access not allowed".

I assume the openssl OCSP query, at least when the -url option is used,
can and probably should pick the domain part out and attach as a "Host:
$domainname" header in the Post.

Regards,
Martin Millnert
