I'm using content negotiation (htaccess Options +MultiViews) to remove specific file extensions from URLs. This works very well as far as I can tell, however it causes me a minor problem with name anchors within a page.
Let say I have linked to www.example.com/page which is what will be displayed in the visitors address bar.
The actual page is www.example.com/page.htm.
This page includes get data, so lets assume the visitor is on the page www.example.com/page?widget=green
If I put a link on the page such as <a href="#top">Back to top</a>, IE and mozilla will both interpret the link as pointing to www.example.com/page?widget=green#top. However Opera will link to www.example.com/page.htm#top.
I believe this is because of the http header "Content-Location: page.htm" that will be returned with the page request.
I can overcome this behaviour by linking instead to REQUEST_URI#top however I have a couple of questions:
Is Opera's behaviour correct? While the browser is informed of the actual content location, the page does return a 200, so should the original URL not be used? Why would Opera also remove query strings from the link?
Should I give up on multiviews and try to use mod_rewrite instead?
