Oh yes.
If you use just /mumbai/ in the from url, this rule matches any URL which contains this word. Also consider you can use a regular expression in the from URL and also some macros in the destination.
As example, now you are redirecting any old URL to the same destionation. But you can build something like:
From URL: /projects/mumbai/
To URL: http://{siteurl}/projects/newsection/{pathltrim /projects/mumbai/}{queryfull}
With this rule the URL:
xyz.com/projects/mumbai/17-site-pages/76-thane-projects
Will be redirected to:
xyz.com/projects/newsection/17-site-pages/76-thane-projects
And so on for any matching URL. That's the ReDJ power...
Kind regards,
