`="/Kooboo"` is better, but still somewhat broad.

Are you sure it is needed in the first place?

If necessary, it could be altered to match only certain tags.

For example, 

    <link rel="Stylesheet" href="/Kooboo-WebResource/Index/jQuery-Styles/20130227" type="text/css" />
could be matched with:

    "html": "<link [^>]+/Kooboo-WebResource/",

(I removed the `[` and `]` around the pattern because, since it's a single pattern, an array is not necessary.)
