Different kinds of URL navigating options in a website

Hey!

Id like to know how the following is done:

if the site address is such as : www.testsite.com
and i browse the site forward usually the url's are as following:
www.testsite.com/about.html, www.testsite.com/members.html, etc...

but what I want to know is, how do they do this to show the page:
www.testsite.com/about/ , www.testsite.com/members/

those are folders? folders having their own index.html? I tried to find such cause
if you type index.html, index.php etc... you would see the same page as well
but I couldnt find the index-file. What technique is this? Are there many more
techniques to navigate through a site like this? If there are, could someone
put an example of those =)?

For example: navigating through GET is like this: www.testsite.com/?page=1

Thanks in advance :thumbsup:

Do a search for mod_rewrite or “pretty URLs”. Usually it’s done in an .htaccess file.

Thank you
