Questions About .htaccess files

[LordGemz]

I have looked and looked maybe I am not asking the correct question. I am wanting to make a .htaccess file. The function of it would need to be the following.

access only available through a particular website. Meaning you can not type the url in directly in the Address bar, you would 1st have to go to the main site, then click on a hyperlink that would take you to the next page, but only accessible through the 1st page. Am I making sense lol. I hope anyone can help me in this area or re-direct me to someone that could possibly help. Thank you for your time and attention.
