Narrative:
While being vectored for a visual approach to runway 18R at cvg, we encountered B757 wake turbulence, resulting in a 40-45 degree bank upset. We had already considered this possibility prior to the upset. Continuous ignition had been turned on. No advisory from ATC as to type of aircraft we were following until later when cleared for the visual. We climbed approximately 400 ft to escape and told ATC. They tried to turn us on a base that would have resulted in about 3-4 mi separation instead of the 5 mi we had at the time of the encounter. You'd think that after all these yrs ATC would quit trying to put us so close to B757's.
