Interactions of virtual photons are analyzed in terms of their parton distribution functions. It is shown that the concept of parton distribution functions is phenomenologically very useful even for highly virtual photonds involved in hard collisions. The role of the longitudinal photons for proper interpretation of the data on jet cross--sections in the region of moderate photon virtualities accessible at HERA is explored.

A review of recent jet measurements of the photon structure from the H1 experiment at HERA. The scale and the virtuality dependence of the effective parton distribution function of the photon is discussed.
