OFF-TOPIC: Help on script

hello everyone,

i'm trying to build a list of sites that i want to ban. i'm getting the
list from the logfile of all the sites that have been visited by all
users.

this is the format of the logfile:

907389399.705 61 192.168.2.57 TCP_HIT/200 2172 GET http://www.excite.com/pfp/excite/images/big_logo.gif - NONE/- image/gif

can someone help me on creating a script that will extract all domains
that has no TCP_DENIED tag to a file with no duplication? i'm not familiar
with sed, gawk or perl so i need your help on this.

i would like the format to be (from the above example) one domain per
line:

        excite.com
        

thanks!
