where i can upload the my .htaccess file in ftp. i have tried 3 times to upload the file. But i am not able to see the file.
files starting with . are hidden, you need to go to the options of your ftp client and check the box which says to see the hidden files.
.htaccess is uploaded to the root of directory you would like the rules to be applied to. If you upload another .htaccess file in a sub-directory, those set of rules are applied to that sub-directory. In order to see them, you need to enable viewing of the hidden files in your FTP client.
