I am using APACHE server and I want to redirect the url to home page if third parameter is invalid number. Code I have written is ::
RedirectMatch 302 ^/app/([a-zA-Z0-9_-]+)/([a-zA-Z_-]+)/?$ /
But its not working. In short:
www.xyz/app/test/3434 :: should pass
www.xyz/app/test/best :: should fail
www.xyz/app/test/34kkk34 :: should fail
You want to redirect when the last part is not a number. Stated otherwise, redirect when there's a non digit somewhere. To get this, you must first match any character including digits.
^/app/[a-zA-Z0-9_-]+/[a-zA-Z0-9_-]*[a-zA-Z_-][a-zA-Z0-9_-]*/?$
Since you don't use any parts of the request in the target URL, there's also no need to capture anything ().
If you don't care about the particular characters, you can simplify the regular expression and just use .* instead of [a-zA-Z0-9_-]*, e.g.
^/app/.+?/.*?[^0-9].*/?$
