[jira] [Commented] (HTTPASYNC-164) ParseException: Invalid protocol
version when using proxy settings
[ https://issues.apache.org/jira/browse/HTTPASYNC-164?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17291312#comment-17291312 ]
Nguyen Ky Thanh commented on HTTPASYNC-164:
-------------------------------------------
I have the same issue, the FORCE_HTTP_1 doesn't work for me.
{code:java}
// My implemetation
final CloseableHttpAsyncClient client = HttpAsyncClients.custom()
.disableCookieManagement()
.useSystemProperties() // Need for proxy
.setVersionPolicy(HttpVersionPolicy.FORCE_HTTP_1) // Need for proxy
.setConnectionManager(asyncClientConnectionManager)
.setDefaultRequestConfig(RequestConfig.custom()
.setConnectTimeout(Timeout.of(defaultClientConfiguration
.getConnectTimeout(), TimeUnit.MILLISECONDS))
.setResponseTimeout(Timeout.of(defaultClientConfiguration
.getReadTimeout(), TimeUnit.MILLISECONDS))
.setCookieSpec(StandardCookieSpec.STRICT)
.build())
.build();
client.start();
return client;
{code}
I even tried to disable the proxy setting:
{code:java}
// code placeholder
java -jar -Dhttps.proxyHost=$HTTPS_PROXY_HOST -Dhttps.proxyPort=$HTTPS_PROXY_PORT \
-Dhttp.proxyHost=$HTTP_PROXY_HOST -Dhttp.proxyPort=$HTTP_PROXY_PORT \
my-app.jar
{code}

> Hi,
> We have upgraded our Apache HTTP Client library from version 4.1.4 to 5.0.3. We are using the async API. Overall, it's working very good. The reason for the upgrade is the need of using the new retry feature. However, we have an endpoint that requires accessing through a proxy. The problem with this one is that it's returning the following error:
> {code:java}

> Is there a way to solve this issue? Any way to restore the previous version configuration?
> Thank you!
