Avoid retrieving truncated book chapters/pages/sections

When modifying the 'sessionid' after each call to oreilly api,
there are calls that are considered not-authenticated and we retrieved
truncated chapters/pages.
By avoiding adding/modifying it, all the calls are correctly authenticated
and we manage to retrieve full chapters/pages.
