[TYPO3] Limited access content log in URL re-direction

[rocky]

Hey list,

I'm a newbie in TYPO3 community. Some content of my web page needs to be 
password protected. The problem is that I want the visitor has access to 
partial of the content even they do not have an account or did not log 
in. After they click on a link, they will be brought to log in page. 
After login they will see the full content. Is that possible any of you 
give me some hints how to achieve this please? Can I do it with new 
login box?

I would really appreciate it if any of you could give me some direction?

Thanks a lot in advance!

Rocky
