Regexp to match domain and subdomains (in Java)

Question

I need to verify if given URL matches my domain mask.

Example: I want to allow only domains which satisfy this \"pseudo-mask\":

https://*.domain.com
         


        

Answer 1

^https?://[^/@]*\.domain\.com(/.*)?$

(The not-/ to stop .domain.com appearing in the path, the not-@ to stop username:password@ abuse.)

Better, though: use the URL class built into Java to parse a URL properly. You can then just read the host property and check that it endsWith your domain.
