What are the meta descriptions for?

[• MaNiC MoE •]

I write the Meta Description in the following way :


<meta name="Description" content="*">


But, what's the following for, then :

<meta http-equiv="Description" content="*">



WHY ARE THERE TWO AND WHAT'S THE USE OF THIS? :confused:

thx, ;)

The second one is the equivalent of setting a page header command in a server side script before sending the page to the browser but only works for some page header commands.

So, when do I really use it?
