When i'm online (on internet) localhost cannot be found

Hi :)
So the problem is this: When i'm on the internet (no matter which network connection i use, it's the same with LAN, WLAN, dialup...) the http://localhost/ is not working, BUT http://127.0.0.1/ is working normally...
The situation is like this:
- When i ping localhost, it works.
- My hosts file is ok i.e. it contains exactly what it should: 127.0.0.1 localhost
- I have no proxies configured
- I get the same behaviour in all browsers

Yuk! :)
Now, this maybe also an important information, though it says nothing: my localhost was working fine, until one day... I wasn't been making any changes or installing something new, it just happened...

Also, i'm "clean" on viruses and spyware...

Any idea? :)

Thanks

My first thought is that your http.conf got changed somehow.  If ping resolves localhost correctly, the browser ought to as well.  Try accessing your server from another device on the network by ip address, and see what happens there.  Also, try using "wget http://localhost/" and see if you get an error.  Also, maybe somehow your loopback device got disabled.  Have you tried "ifconfig lo up" ?

Thanks, Smidgie, but (oops! :))i forgot to mention that i'm using windows...
Also, i didn't explain one more thing correctly, the pinging: if i ping it as 'localhost' i get "no reply", it works only when i ping 127.0.0.1

Thanks

Well, Smidgie gave me the hint i.e. the keyword "loopback", so i'm giving him the points.

Finally, it turned out that, after i uninstalled the ipv6, everything works fine... Don't ask me why :)
So, the solution to this problem was to type 'ipv6 uninstall' in the command prompt.

Best wishes! :)

Oops...  I forgot Windows has a hosts file, too.  Doh!

Thanks for the points, and good job on the fix!
