What are the options in the stylesheet used for? For example, the Dell homepage has this link with three options:
<LINK REL="STYLESHEET" TYPE="text/css" HREF="http://www-cdn.dell.com/content/public/css.aspx?c=us&l=en&~set=storm81_hp">
I know that a single parameter when changed can be used to force the browser to re-select the stylesheet. For instance:
eg: http://sstatic.net/stackoverflow/all.css?v=a6754691e23a
but the Dell link obviously aims to send the parameters back to the server for processing. Is this used to select a specific version of the stylesheet? In that case, why not send the target stylesheet first?
Surprise...
