So I learned from this handy guide how to use .htaccess to redirect pretty URIs like foobar.com/baz to specific content that may reside at foobar.com/bazheader345.php?user=baz.
What if I'd like to do the opposite? My anchors are static but I have a lot of content in different files - and none of them has a particularly pretty name. Say I have a page at foobar.com called 123.html and would like the location bar to remain http://foobar.com despite the navigation between files that the user does.
Can this be done via changes to .htaccess? Or simply Javascript?
If it is possible, would it interfere with the browser's history states?
