Invalid URL

when i am browing my site it gives me invalid url even when i am trying to login my webmail it gives me invalid url and after refresh that page it worked fine

the error like this

It seems like you are browsing through an proxy of some kind to me, is that right?
I've never seen any "Reference ..." message from Apache.

EDIT: a tiny Google research shows that this kind of errors is caused by local errors, often page cache and cookies (clear them in your browser) and local DNS cache (clear it with ipconfig /flushdns or reboot your system). No idea of where the "Reference" message comes from anyway... anyone has a hint?

Hello M8 I am glad that i got reply

and i am reborted my pc and i am browsing it directly

Invalid url came back right after it said Network error, cannot connect to the network. I would click on the green check mark and then it would proceed to save and then Network error again.

ARGHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
