  We discuss the shape of the interaction region of the elastically scattered
protons stipulated by the high-energy Pomeron exchange which turns out to be
very similar with the shape of the static string representing the confining QCD
flux tube. This similarity disappears when we enter the LHC energy region,
which corresponds to many-Pomeron exchanges. Reversing the argument we
conjecture a modified relationship between the width and the length of the
confining string at very large lengths.
