Send "410 Gone" response for URLs that are a "c" or "g" followed by digits

Question

Is there anything i can use in my htaccess to send 410 code to all the links but not some links ?

Example:

I would like to 410 this urls (List is about 40k links)

www.example.com/c1
www.example.com/c2
www.example.com/c3
www.example.com/c4
www.example.com/g1
www.example.com/g2
www.example.com/g3
www.example.com/g4
and so one....

but this links should not come 410, anything that start with c or g

Like:

www.example.com/categories/
www.example.com/concreate/
www.example.com/colombs/

Right now I am using this code in my .htaccess file but this also giving 410 to above links.

RewriteEngine On
RewriteCond %{QUERY_STRING} c
RewriteRule .* - [G,L]
ErrorDocument 410 default

Any help would be much appreciated.

Answer 1

RewriteCond %{QUERY_STRING} c

Not sure why you are referencing the QUERY_STRING here? Your URLs don't appear to contain a query string?

It looks like the URLs you want to block start with a c or g and followed by a digit (I'll assume 1 or more digits). In which case, try something like the following:

RewriteEngine On
RewriteRule ^[cg]\d+$ - [G]

No need for the L flag with G.

Answer 2

user82217 provided a fine solution using mod_rewrite. You can also use mod_alias to do it:

RedirectMatch gone "/[cg]\d+$"
