Correction, the problem has not gone away, because there is no wildcard redirects in Webflow.
For example, I need
http://samliew.com/blog/2015-02/to-those-starting-national-service/
to redirect to:
http://blog.samliew.com/2015-02/to-those-starting-national-service/
Therefore, I need to capture any request going to samliew.com, check for pattern using a htaccess file, then perform the redirect to the blog. If visitor wasn’t heading to the blog, then it just redirects to my site as usual.
I also have other blogs that I migrated from directories to subdomains before moving to the Webflow site, and therefore needed to “capture” users headed to the old subdirectory URLs to redirect them. That was the real reason why I split up the www and non-www domains.
