I tried many solutions to this problem without success. When i develop a site for a client of mine i have to put it live on his domain while i'm developing it but i also want to prevent everyone to see the site while in costruction. I don't want to put all the public directory stuff under a subdirectory (for example a "test" subdir) of the apache document root 'cause when the site will be published under the document root i will have to change relative urls that i wrote for example in the boostrap file. How can i solve this?

get familiar with .htaccess files and functionality they provide
