How to use mandatory proxy of /a/b to /x/y

[Asilent]

I want to let path /a/b redirect to service /x/y. Does Kong already support this action?

I am not 100% of what you are asking - in Kong, paths are managed by Routes while Services usually refer to "hosts". Could you give us a more specific example of what you want?

In any case Kong does not have a plugin that suits your needs, you can try with a community plugin. For example here's one redirect plugin from stone-payments:

I guess you mean to use: HTTP Location header with 301, 302, 303, 307, and 308 status codes?

redirection: send response to client to go another place
rewriting: change the uri before processing any further (e.g. before routing for example)

What I described was a little confusing. Just like a request come from www.x.com/a/b, I want to send it to www.y.com/c/d.
Now I find Kong can send a request like /a/b/c to /b/c by stripping path, but it can't meet my requirement.

No, just a proxy. You can think that I want to anonymize real path, so I expose a virtual path to client. The real path is invisible to the user.

Kong by default is only able to "strip" parts or the full path of a request. In order to make a redirect to a different path you will need to use a plugin, like the one I linked on my first response, or else make a custom plugin which suits your needs.
