why do we need a portal server, why can't an application server do the same job?

What Portal provides is

authentication

authorization,

user management,

security ( SRAP),

content presentation frame work ( URL Scraper provider, RSS provider and JSP provider )

dynamic vpn ( through netlets you can integrate any tcp based network application )

Wireless portal :-),

and a variety of other features ..

I don't believe app server provides all these features. Requirements of these features necessitates a portal market which the portal server addresses.
