Thanks for reply After consulting with cliet, when i told him that this is against human rights. he said to me that he wants to know only domain names not full URL with query data. he wants to know the domain names like songs.pk, mp3pk.com, yahoo.com, youtube.com etc atcually he told his employees not to use unnecessary sites at working time because it effects the work. after long waiting he decide to get such application that could tell him about the domain names opened on particular system. when he check out at the server he get all the url requested and found that employee open youtube.com and watch the vedio at working time. so he wants to stop that particular employee. thats why he wants to get this application.
