Google has removed the http:// in Chrome’s address bar. This change, made in a recent developer version, has caused some discussions. For most users, the http:// scheme is not important, as all browsers add it automatically in front of every address you enter.
HTTP is short for Hypertext Transfer Protocol and is the standard protocol for requesting web resources from a server. Google thinks that displaying the scheme is useless and can thus be omitted. As many applications recognize web addresses via their http:// prefix, Chrome adds this prefix to the URL when you copy it from its address bar. https:// and ftp:// will get displayed as usual.
