Why there is no Regex Support for excludeList of nonProxyHost

[kasingal]

Code at line below should be enhanced:
https://github.com/eclipse/jetty.project/blob/8102378e2d24b8117ed3a545c7579f79d35fc45a/jetty-client/src/main/java/org/eclipse/jetty/client/ProxyConfiguration.java#L180

Generally nonProxyHosts gets defined with wildcards like *.abc.com|*.svc.local etc.. so .equals doesn't help !
And apparently Jetty Client doesn't have any support for wildcard list of nonProxyHosts !!

PS: reactor-netty handles it pretty well, refer below:
https://github.com/reactor/reactor-netty/blob/main/reactor-netty-core/src/main/java/reactor/netty/transport/ProxyProvider.java#L310

What version of Jetty?

[kasingal]

Any version till date.. there is no support for the pattern match there on the line I just tagged to the ticket !
Better to have it enhanced in 9.4.x and higher versions !

I would like to work on this issue.
Is targeting jetty-10.x still the way to go about it? Thanks

[sbordet]

Yes, please target branch jetty-10.0.x. Thanks!

Hi - I opened PR #10538. First contribution to this project - feedback is always welcome.
Currently only allows for wildcards at the start and end of the host. This matches the behavior of the jdk default via nonProxyHosts, see:

The patterns may start or end with a '*' for wildcards.
(https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html)

I think this satisfies most use cases.

If we (you) also want to support wildcards in the middle maybe something like this works better:

      String hostRegex = Arrays.stream(host.split("\\*"))
        .map(s -> {
            if (s.length() > 0) {
                return Pattern.quote(s);
            }
            return s;
        })
        .collect(Collectors.joining(".*"));
