Bug ID: 57691
Summary: mod_proxy/proxy_util confuses UDS scheme with HTTP
scheme when using RewriteRule
Product: Apache httpd-2
Version: 2.4.12
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy
Assignee: bugs@httpd.apache.org
Reporter: dferra...@gmail.com
Problem: mod_proxy or proxy_util are confusing a fcgi with a http one
Scenario: The only scenario I have seen where that happens is when you proxy to
uds through mod_rewrite.
Example:
ProxyPassMatch ^(.+\.php)(/.+)?$
"unix:/opt/apache/httpd/logs/fpm/owncloud.sock|fcgi://localhost/var/www/" <--
WILL WORK
In the same exact context (VirtualHost):
RewriteRule ^/(.+\.php)(/.+)?$
unix:/opt/apache/httpd/logs/fpm/owncloud.sock|fcgi://localhost/var/www/ [P,L]
<-- it seems proxy_util will interpret the client is requesting:
/unix:/opt/apache/httpd/logs/fpm/owncloud.sock|fcgi://localhost/var/www/
As you can see in the trace log bellow it seems like a "/" has been prepended
to the uds scheme turning it into a http scheme request:
