There are four distinct types of entries which differ in their structure.
What is common to all of them are timestamp, sessionkey and type of action
as the first three entries.

 <timestamp> the UNIX time in seconds since 70/1/1
 <sessionkey>the SessionId
 <action>    a two-digit abbreviation which describes the subtype

----------------------------------------------------------------------------

New Sessions

Sequence: <timestamp> <sessionkey> <action> <host> <referer> <URL> <user
agent>

    <action>  covers 00 to 09 to describe the subtype; till now, only 00 is
                                                                     in use
       <URL> GOId or name of entry point
      <host> is the name or IP-address of the remote host
   <referer> the referring page
 <user agent>the user's browser

This info is logged only with the start of a new session since it is always
accessible via the sessionkey.
