I created a folder named 'support' inside /public_html/ directory. and asign a subdomain 'support.mysite.com' to this directory. (I have to give this to another person) I want that second person can only login this dir using ftp software and not able to see any files outside this (support) folder. This pass will only for developer and not for visitors. Site visitors will see the site 'support.mydomain.com' normally. Is it possible? How? (reason: If the person see my others files then he may copy that)
are you managing this from Plesk? in plesk you can create a subdomain and create a new user account, that way they only manage that area of the site and not be able to see the rest... the admin (yourself) can still access everything i believe other cpanels can do this too but i work with plesk and 100% certain on this
