It is well known that BFKL gives anomalous dimensions of twist-2 operators of spin j
in the "BFKL limit'' $g^2\righarrow 0,\omega\equiv j-1\righarrow 0,{g^2\over\omega}$ fixed.
I demonstrate that such limit describes the non-local light-ray operators and
present the results of calculation of two- and three-point correlation functions of
these operators in this limit. The calculation is performed in ${\cal N}$=4 SYM but the
result is valid in other gauge theories such as QCD.
