We actually need a redirect for the .html version to the bedrock version. Just proxying history.html calls to bedrock will cause there to be multiple possible urls and the SEO people dislike that.

```apache
RewriteRule ^/(\w{2,3}(?:-\w{2}(?:-mac)?)?/)?about/history(\.html)?$ /$1about/history/ [L,R=301]
RewriteRule ^/(\w{2,3}(?:-\w{2}(?:-mac)?)?/)?about/history/$ /b/$1about/history/ [PT] 
```
