|Whatever your problem is it is not got anything to do with http://www|
HTTP stands for Hyper Text Transfer Protocol and it is the default protocol all browser use in the absence of any other stipulated protocol like FTP = File Transfer Protocol or SMTP = Simple Mail Transfer Protocol.
Again WWW is the default for a properly constructed URL. It is what comes after the WWW that is important. If you change any of these defaults then you are just making trouble for yourself.
More details of how you are configuring this web page would be useful. Are you hosting it yourself on your own home network or is it being hosted externally by a web hosting company.
Bear in mind that you cannot access your own web page from within your own network using its URL. For that you need a router that has local loop-back and very few do. The only one I know of that do that are Belkin routers.
To Access your web page from the same network the web server is running on you need to use Local Host which is t 127.0.0.1 or the actual IP address of the computer that is running the web server.
