.css?1 - what does this mean?

[robertnorgren]

Hi,

I'm using a Facebook comment plugin with requires some extra work every time I update the stylesheet.

The stylesheet is linked within the plugin and currently the URL looks like this:
http://www.robertnorgren.com/css/fb_comments.css?48


Everytime the stylesheet is updated, you need to increase the number past the questionmark.


I'm hoping someone could briefly explain why and also if there's a workaround to get rid of this requirement?




Thanks!

Is it a requirement of the facebook plugin to have a number associated with the css? Could you just use fb_comments.css and everytime you update it you just overwrite the current one?

I don't use facebook myself but it seems a bit odd to me that you'd have to have a number in there.
