Best Way to run MMORPGs on dial-up?

At college I found the MMORPG battlestar galactica online. The only problem is that i can only play at college since i have dial-up at my house. Is there anyway i can save the temporary internet file for the online game onto like a flash drive and save to my computer at home if this is even possible? If not what other things could I do to play this game on dial-up? (Yet again even if i can play this at my house with dial-up)
