Jim Munro: Welcome Fatih. :)<br /><br />At first I thought this was an odd question but then I checked the cache for microsoft, yahoo, google, amazon, twitter, FB etc and found the caches recorded were all between three and ten days old. I have no idea what this means though, mate, I am not an expert but let's wait and see what others have to say. ;
Fatih Ahmad: thank you Jim, ;yeah, this is why I have posted this question here and look like there is no one out there who can throw some more light on this, or can tell us some more details, ;
