After updating from 2.4.59 and restarting apache, I get a "Bad Request" error when visiting FCGI pages on my website. I'm using Unix Domain Sockets (as files instead of network ports) for apache to communicate with the FCGI daemon. Reproducible: Always Steps to Reproduce: 1. Use a line such as `SetHandler proxy:unix:/somewhere/php-fcgi.sock|fcgi://` in an apache vhost config. 2. Visit the website of the vhost on a page that uses the handler. Actual Results: A barebones HTML page that says "Bad Request" with HTTP code 400 Logs (error_log) that say things like `[proxy_fcgi:error] AH01059: error parsing URL //: Invalid host/port` Expected Results: The output of the FCGI script requested. No error log. Upstream bug report (reopened): https://bz.apache.org/bugzilla/show_bug.cgi?id=69160 Circumvention is as easy as adding a duummy domain to the configuration, for example: -SetHandler proxy:unix:/somewhere/php-fcgi.sock|fcgi:// +SetHandler proxy:unix:/somewhere/php-fcgi.sock|fcgi://apache_bug_69160
