How to remove trailing slash from URL in magento

Hi Friends

Does anyone help me to remove trailing slash from the URL in magento?

currently my URL is like

http://www.websitename.com/index.php/

i want to change this URL to http://www.websitename.com/index.php

Thanks in advanced

That's kind of strange.. is index.php a directory? If not, it should not have a slash after it. How are you ending up at that URL?

Sometimes some PHP programs do that as an alternative to URL rewrite. If URL rewrite is not available then they will just put a folder after index.php and just read the url ($_SERVER["REQUEST_URI"]) and parse that back into $_GET data or some other global vars. The server still loads index.php, however it allows the script to have cleaner/shorter urls.

You might not like the look of the trailing slash, but it is probably there to clean your urls for links. It shouldn't hurt anything and will take an url like this:
/index.php?page=1&product=1118&action=add
and change it into something like:
/index.php/1/1118/add
