For (1) how does the httpd send the information that it wants to use the 
result list from a previous connection? Is it going to use a new LDAP 
control? Or would there be a session ID?

If we implement (2) does it mean the pages still need to be accessed 
sequentially, or can we jump to any random page?

Also if I understood correctly the LDAP connections are made using user 
credentials, not Directory Manager, so things like nsslapd-sizelimit 
will apply. Does it mean a non-admin cannot browse the entire directory?
