Description

Error

MediaWiki version: 1.35.0-wmf.15

message

PHP Warning: Cannot modify header information - headers already sent by (output started at /srv/mediawiki/php-1.35.0-wmf.15/includes/libs/http/MultiHttpClient.php:390)

Impact

There's not huge number of these, but as it seems like a clear programming error, I figure it's best to report so it doesn't get lost. Unless something changes, I"m not treating this as a train blocker.

@WDoranWMF @daniel I saw some code going by from Daniel this week that address this or a similar issue. Can you confirm and de-duplicate or pick up further as needed?
