  We consider the T-matrix near the unitarity limit and the energy dependence
of the saturation momentum. We discuss the solution to the Kovchegov equation,
or equivalently, to the BFKL evolution in the presence of a single saturation
boundary. We include some of the correlations missed in the Kovchegov equation
by solving the BFKL equation in the presence of two boundaries. The T-matrix
now turns out to be frame-independent, which was not the case for the solution
in the case of a single boundary, and it doesn't show the scaling behavior of
the solution to the Kovchegov equation. We find for the saturation momentum an
energy dependence which differs from the one following from the Kovchegov
equation.
