Content-Location support
Opera 9.0 released. Is that good news or bad news? Well it depends on the side of the coin you are looking at, as usual. From the HTML, CSS, AJAX, whatever presentational, then it is good news. However if you look from down under (not Australia, from the protocols side), then you will notice that you are no longer able to navigate this weblog directly, as they removed support for Content-Location, mimicing that way the other browsers following the common trend of violating RFC2616#14.14 to accomodate badly configured web sites.
See the Content-Location test, recently updated with this bad news.
