SolrJ 9.2.1: How to Use HTTP Proxy

["Pieper, Stefan" <St...@coremedia.com.INVALID>]

Hi all,

While doing an upgrade from Solr 8.11.2 to 9.2.1 I bumped into an issue with proxy configuration for SolrJ and though I dug deep into the code I'd like to make sure I didn't miss something obvious.

It's about defining a proxy host for SolrJ requests. It seems like HTTP/2-based Solr clients (Http2SolrClient etc) cannot be configured to use a proxy. For HTTP/1 clients this was recently solved via SOLR-12848. But environment variables "http.proxyHost" etc are not applied by Jetty clients which are used for HTTP/2 communication. Configuration of the Jetty client through org.eclipse.jetty.client.HttpClient#getProxyConfiguration() is not possible, either, since Http2SolrClient#getHttpClient() is package-protected.

Do you know of any way around this? Or is it a gap in the Solr API (for which I'd create a Jira ticket then)?

Thanks!
Stefan

Hi Kevin,

Right, just two days before my own ticket (and five days after I last checked) this other ticket has been created. Thanks a lot for spotting the duplication! Looking forward for a fix.

Best,
Stefan

I don't see a way around this, but I saw
https://issues.apache.org/jira/browse/SOLR-16859 was created.
