I just checked an .htaccess file with some custom redirects. There are two redirects i dont fully understand:
RedirectMatch 301 ^/news/([0-9]+)-(.*) /blog RedirectMatch 301 ^/news/([a-z]+)-(.*)/$ /blog/$1
Both redirects are redirecting the subfolders or pages inside the news directory but i cant fully grab how because i dont understand the following parts "[0-9]+)-(.)" and "([a-z]+)-(.)". What do they exactly mean?
Thank you so much for your help and best regards.
