you use Apache::Session or CGI::Session to do that transparently.

your java servelet example seems to be using a framework, while  
mod_perl is a platform.

you might be wanting to use something like catalyst which can run on  
modperl and has the facilities to do what you want built in.

session handling isn't built into mod_perl, because that would lock  
people into a certain way.  instead you use either Apache::Session or  
CGI::Session, or one of the numerous variants.

They all use the same model:

	session id comes from client cookie
	session id loads / saves a session variable to your LAN.  either on  
the same machine in a file, or on a database on your local network

> request.getSession().setAttribute("my_remote_user",<uid of the  
> authenticated

that is very likely just wrapping several functions in one line.

request.getSession() probably wraps a routine to get session id based  
on some client cookie value
