Build:

This is the source of my blog post.

The posts in source/_posts are built into html files at build time. Azure listens to git commits and then runs deploy.sh which installs hexo and generates html into ./public with hexo. the web.config (which is what Azure uses as a .htaccess file) rewrites all urls to the public directory. Any 404's will be redirected to 404/ which will actually be public/404/index.html in the filesystem
