Version 4.5.18:
When using --url-alias with mod_wsgi-express and the target of the URL doesn’t \ 
exist, it will now be assumed that it will be a directory rather than a file, \ 
when finally created. This is to accomodate where may have used --setup-only \ 
option or setup-server command to pre-generate config files before the directory \ 
is created.
