This is the PATH to your web's CGI-BIN directory. The UNIX system upon which the HTTPD server runs, contains a hierarchial directory structure which is much like a tree, with a root directory for the system, and a directory for each user who has an account or username on the system. Some operating systems refer to what UNIX calls "directories" as "folders" instead.
When you login directly to the UNIX system, you login to your own $HOME directory, where you own and can manipulate all the files. Other users own their own $HOME directories. Inside your $HOME directory, there are subdirectories such as "web". You can CD into these subdirectories just as you would at the DOS command line prompt. The only difference is that UNIX uses a "/"(forward slash) where DOS uses a "\" (backward slash). Your Web Site's ROOT (top level) directory is located in the directory:
/u6/iserv/www.four.net/users/yourusernamehere
if you're a FOURnet SLIP/PPP customer, or in the directory:
/u6/iserv/yourvirtualdomainnamehereif you're a Virtual Domain customer. This is the ABSOLUTE directory path. The relative ROOT directory for your Web pages is normally found if you type "cd web" when you first login: (~yourvirtualdomainnamehere/web).
For Virtual Domain customers, CGI-BIN directories can be found at:
~yourvirtualdomainnamehere/web/cgi-bin
For customers who are setup for web ftp access, you can disregard the above information, as you will be logged into your web root directly when you login to your ftp account.
To determine whether you're logged into your web root directory, type "dir" or "ls -al". There will be a file called "Welcome.html" in your web root directory. You will be placing your HTML files in this directory, and in subdirectories below your web root (if you choose - it is not necessary to use subdirectories or folders, but it can keep maintenance easier if you maintain some structure to your site.) When logged in using ftp, if you type "ls -alF" you will see directories or folders listed appended with a "/" character after the name. This indicates that this is not a filename, but a directory. Additionally, you will see characters at the beginning such as "drwxr-s-r-x". If you see a "d" at the beginning of the line, this also indicates that this is a directory. "-rw-r--r--" at the start of a line would indicate a filename. This also indicates appropriate file permissions for a file such as Welcome.html. For a file to be readable by the world, there should be three "r" characters. See the Unix chmod command, or a book about using web servers for additional information about file permissions. Make sure that your file doesn't have the "w" bit set after the third "r" or it may be writable by anyone - this means that others may be able to delete or write over your page!

NOTE: Be sure to replace the "yourvirtualdomainnamehere" and "yourusernamehere" in the above examples with your actual username or domain name.
