../ refers to the current directory

here you are not using any file name. which defaults to the default file
used for index file.

i would recommend doing something like this tough :

<a href="/index.php?page=products">Products</a>

As some hosts could be configured to have index.php as default documents,
some other index.php3. and so on.

It's best to always point to the file that way you can avoid weird
surprises.

Hope this helps.
