title: Required entering a valid URL when installing Magento 1.9.2?
body: <p>When installing Magento 1.9.2, I couldn't go to the next step because a URL validation occurred that required entering a valid URL. Older versions of Magento didn't have this issue. I found the solution <a href="https://stackoverflow.com/questions/31670285/please-enter-a-valid-url-protocol-is-required-http-https-or-ftp-in">here</a>. But I want to know the reason for this. Is there any security issue here?<br>
  Can you explain this?</p>
