Labels: pull-request-available (was: )
> More transparent proxy handling for HTTP redirects
> --------------------------------------------------
>
> Key: SPARK-45468
> URL: https://issues.apache.org/jira/browse/SPARK-45468
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 3.5.0
> Reporter: Nobuaki Sukegawa
> Priority: Major
> Labels: pull-request-available
>
> Currently, proxies can be made transparent for hyperlinks in Spark web UIs
> with spark.ui.proxyRoot or X-Forwarded-Context header alone. However, HTTP
> redirects (such as job/stage kill) currently requires explicit
> spark.ui.proxyRedirectUri as well for handling proxy. This is not ideal as
> proxy hostname may not be known at the time configuring Spark apps.
> This can be mitigated by 1) always prepending spark.ui.proxyRoot to redirect
> path for those proxies that intelligently rewrite Location headers and 2) by
> using path without hostname (/jobs/, not https://example.com/jobs/) for those
> proxies without Location header rewrites. Then redirects behavior would be
> basically the same way as other hyperlinks.
> Regarding 2), while hostname was originally required in RFC 2616 in 1999,
> since RFC 7231 in 2014 hostname can be formally omitted as most browsers
> already supported it (it is rather hard to find any browser that doesn't
> support it).
