title: curl response says "HTTP version not supported", error 505
body: <p>I made request using curl, the response says that HTTP Version not supported, error 505. What are the steps to make HTTP Version supported. </p>
  
  <p>After googling i get, the i should use curl --http2.0 to make it work, but my curl version is not supporting that option, as it is added in curl 7.33, whereas i am using curl with version: curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.14.0.0 zlib/1.2.3 libidn/1.18 libssh2/1.4.2</p>
  
  <p>Now, should i upgrade my curl or is there any other way to make it supported or am i missing something in my request(sorry, but i am not able to show the request).</p>
  
  <p>If i need to upgrade it, then please specify me the way how to upgrade curl to version 7.33.0, i am not getting any proper way to do it.</p>
