The HTML content session is proceeded when client does not mark checkbox "I am using Internet Explorer 3.01 or higher..." at "Databases exposured list" page. This session is used as by default.

During the session clients receive only hypertext and pictures in JPEG format. It means, that almost any computer with different operational systems and Internet browsers can be used at client site. Contrary to Active Session, it is impossible to implement some kind of searches, sort found results, load extraction, print, save chemical structures and spectra in application-readable formats. Net traffic is much more higher, than under data sending via Active Session.
