爲什麼不能捲曲/ OpenSSL獲取chrome + firefox可以訪問的網站？

Question

無論是在我的程序（它使用OpenSSL的），並捲曲，我不能獲取一個網站：

 
$ curl -v https://registration.experient-inc.com/HTMLProduction/ShowCES131/ConfirmationImages/CES131_Header.JPG 
* About to connect() to registration.experient-inc.com port 443 (#0) 
* Trying 12.153.51.94... 
* connected 
* Connected to registration.experient-inc.com (12.153.51.94) port 443 (#0) 
* successfully set certificate verify locations: 
* CAfile: /usr/ssl/certs/ca-bundle.crt 
    CApath: none 
* SSLv3, TLS handshake, Client hello (1): 
* Unknown SSL protocol error in connection to registration.experient-inc.com:443 
* Closing connection #0 
curl: (35) Unknown SSL protocol error in connection to registration.experient-inc.com:443 

由於每一個不同的問題，我將發佈一個直接OpenSSL的調用會發生什麼：

 
$ openssl s_client -host 12.153.51.94 -port 443 
CONNECTED(00000003) 
write:errno=104 
--- 
no peer certificate available 
--- 
No client certificate CA names sent 
--- 
SSL handshake has read 0 bytes and written 320 bytes 
--- 
New, (NONE), Cipher is (NONE) 
Secure Renegotiation IS NOT supported 
Compression: NONE 
Expansion: NONE 
--- 

任何想法爲什麼發生這種情況/如何解決它？

顯然，Web服務器根本不支持SSLv2。即它甚至不支持SSLv2你好。強制curl或OpenSSL在正在運行的查詢中使用SSLv3 +。
