In the polar coordinate system, the polar coordinate equation of circle C is ρ=4cosθ. Taking the pole as the origin and the direction of the polar axis as the positive direction of the x-axis, establish a plane rectangular coordinate system with the same unit length as the polar coordinate system. The parameter equation of line l is $$\begin{cases} x= \frac {1}{2}+ \frac { \sqrt {2}}{2}t \\ y= \frac { \sqrt {2}}{2}t\end{cases}$$ (t is the parameter).

1. Write the rectangular coordinate equation of circle C and the general equation of line l.
2. Given point M($$\frac {1}{2}$$,0), line l intersects circle C at points A and B. Find the value of ||MA•MB||.
