Allow Custom URL Rewrite Handler for Database
Allow installation of a GAC custom rewrite handler for doing URL rewrites on Web Apps using a database backend.
Thanks for bringing this up once more. We will have an internal conversation again about implementing for App Service.

Having recently migrated a site from another hosting provider to Azure, I was extremely disappointed to find that this feature wasn't already available (having written a web.config file due to the lack of .htaccess support) .
The equivalent in Apache Hosting (.htaccess - RewriteMap - dbd And fastdbd) is widely supported by numerous hosting companies.
