Hide the file name in the URL

what is the best method of hiding the file name in the URL from a developers side (who has no control over the server), for example if the site is www.123.co.za/contact.htm - i wan the user to only see www.123.co.za. an example of such can be seen here http://www.groupon.co.za

ways i know of is using one page and dynamically loading page content using ajax the other is frames

(server options like mod_rewrite i cant use as i dnt have access to or control 开发者_如何学运维over the server)

They are using index pages. That means they have a page such as index.html, index.php, or index.aspx, etc. All you have to do is create a directory (for example, 'contact') and put a file named 'index.html' within that directory. Then you can view www.123.co.za/contact/index.html as www.123.co.za/contact. Note that your allowable index page names may vary. If index.* doesn't work for you, contact the host and ask (sometimes it's default.*).

The catch to this method is that your page is now viewable by at lest three URLS (www.123.co.za/contact, www.123.co.za/contact/, www.123.co.za/contact/index.html). This can hurt your site in search engines for you may get penalized for "duplicate" content. You could solve this issue with mod_rewrite but seeing as you can't use that, you can't prevent the aforementioned scenario.
