WSO2 ESB blocking address by proxy

Question

In my usecase i have a black-list, stored inside the WSO2 ESB registry, containing a list of forbidden REST URL paths (ie /myservice/myethod1; /myservice/myethod2; /myservice/myethod3;).

I need to have a proxy able to block all the incoming requests having an url containing one of the black paths listed. For example, proxy must to block an http request having this url:

http://localhost:8280/myapplication/REST/myservice/mymethod1/param1/param2

What's the best way to do it?

Does WSO2 ESB have a security policy which already do this?

or

Can i do this simply using the proxy configuration?

or

is writing my own custom mediator the best way ?

Answer 1

You could use Filter Mediator or Conditional Router Mediator if you can manually specify the blacklisted urls in the proxy.

If you need to read the urls from a file, I think it's best to go for a custom Class mediator.
