So you don't want people to be able to tell what your individual pages are called and want to restrict the way that people access your pages? Well this page and the one following are an actual example of how to do it (and also shows how anyone can relatively easily bypass such restrictions if they really want to).
The name of this page does not appear in the address bar because the page name of the page you are reading is not index.html and it's not even in the 'hidden' directory. The reason that you can't see the name of this page is because this page is inside of a frameset (which is called index.html).
This doesn't look like its a frame page because there is in fact only one frame within the page. You can look at the source code for the single page frame definition by selecting 'view/source' from the menu bar of your browser. From this you can find out the name of this page. By placing all of your pages within a single frame frameset, you can avoid displaying the name of each page within the address bar.
Normally in this situation, you can easily access the source code for the individual frame within the frameset by right clicking and selecting 'view source' from that menu. You probably cannot do that on this page because I have included oncontextmenu='return false;' in the body tag which completely blocks access to the context menu both from the right mouse button and the keyboard in both Internet Explorer and Netscape (much more effective than using a no right click script). I apologize to those who rely on the context menu for site navigation for any inconvenience. Of course, if you know what you are doing you can still access the source code from the copy that has been made on your computer by the browser so while the source of this page is concealed, it can still be accessed by someone who knows what they are doing even if they are using Internet Explorer or Netscape as their browser.
For those using Internet Explorer, disabling the context menu on this page also means that they cannot right click any of the images on the page to save them on their computer. Anyone can however still access copies of the pictures on their computer if they know where to look or use a different browser.
