HTTPBuilder with Proxy

http-builder-with-proxy.groovy

@Grapes(
    @Grab(group='org.codehaus.groovy', module='http-builder', version='0.4.1')
)

import groovyx.net.http.*
import static groovyx.net.http.ContentType.*
import static groovyx.net.http.Method.*
import org.apache.http.auth.*

def http = new HTTPBuilder( 'http://www.ipchicken.com'  )

http.client.getCredentialsProvider().setCredentials(
    new AuthScope("myproxy.com", 8080),
    new UsernamePasswordCredentials("proxy-username", "proxy-password")
)

http.setProxy('myproxy.com', 8080, 'http')

http.request( GET, TEXT ){ req ->
    response.success = { resp, reader ->
        println "Response: ${reader.text}"
    }
}

will it work in conjunction with my provider advanced.name/ru ?
