Given a language L that is online recognizable in linear time and space, we construct a linear time and space online recognition algorithm for the language L·Pal, where Pal is the language of all nonempty palindromes. Hence for every fixed positive k, Pal k is online recognizable in linear time and space. Thus we solve an open problem posed by Galil and Seiferas in 1978.
