Setting maximum http connections for Apache fluent executor

Question

Apache fluent API allows simple one-line http calls like:

String content = Request.Get(url).execute().returnContent().asString();

Which is executed by a ...fluent.Executor, whose javadoc says:

A PoolingHttpClientConnectionManager with maximum 100 connections per route and a total maximum of 200 connections is used internally

I would like to change the maximum connection parameters to be used for a specific call, but I can't find a way to access the connection manager used by the above code. I have tried:

Executor.newInstance().execute(Request.Get("")).returnContent().asString();

but there is no way to change these parameters on the Executor returned by Executor.newInstance().

Is there is way to use the fluent API but with custom maximum connection values?

Answer 1

One can bind an instance of the fluent executor to an arbitrary HttpClient instance

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
CloseableHttpClient client = HttpClients.custom()
        .setConnectionManager(cm)
        .build();
cm.setDefaultMaxPerRoute(15);
Executor.newInstance(client).execute(Request.Get("/")).discardContent();
