try this -
$ sort -k 4 logfile | awk 'NR==1{prev=$4;txt="session."$4"."$6"."$7;printf("%s\n%s",txt,$0);getliine}{if (prev !~ $4){txt="session."$4"."$6"."$7;printf("%s\n%s",txt,$0);prev=$4}else {print $0;prev=$4}}'

SESSION_ID(3)								 1							     SESSION_ID(3)

session_id - Get and/or set the current session id

SYNOPSIS
string session_id ([string $id]) DESCRIPTION
session_id(3) is used to get or set the session id for the current session. The constant SID can also be used to retrieve the current name and session id as a string suitable for adding to URLs. See also Session handling. PARAMETERS
o $id - If $id is specified, it will replace the current session id. session_id(3) needs to be called before session_start(3) for that purpose. Depending on the session handler, not all characters are allowed within the session id. For example, the file session handler only allows characters in the range a-z A-Z 0-9 , (comma) and - (minus)! Note When using session cookies, specifying an $id for session_id(3) will always send a new cookie when session_start(3) is called, regardless if the current session id is identical to the one being set. RETURN VALUES
session_id(3) returns the session id for the current session or the empty string ( "") if there is no current session (no current session id exists). SEE ALSO
session_regenerate_id(3), session_start(3), session_set_save_handler(3), session.save_handler. PHP Documentation Group SESSION_ID(3)
