1 - hash function has to generate unique value per string. if you are saying that i will use strings and i am pretty sure that they will not the same size and their 1st, 7th and 11th numbers will not be same! i then say thats ok, but i would not call that a hash function.
besides that i remember i was talking about saving hash values of the links, what changed your mind? you were against that idea.
3 - i will look the code more carefully.
4 - letme tell you some criterias;
if you can use this as ref db like i did, you may use it in couple of places, if you provide abstraction, you can change algorithm of saving method, like using hash or saving some other container other than set for example.
