Copy data that every user searches inside a network and store data in our network server locally.

How can we store all the searched result in our network so that every time we search the same thing that can be used from own server. For eg there are 30 pc in an office. employee no. 1 searched some data in internet and now if another employee wants to visit same page or download same file. First question can we save the data like that ? Second question can we give that employee our own saved data ? We want to store all the searches and store them locally so that there is less traffic in main network and faster speed for all.
