Questions tagged [apache2]

The Apache HTTPd Server. When asking questions about virtualhosts, please include the output of the following command: "apache2ctl -S" (or "httpd -S" depending on your OS)

The Apache HTTP Server is a popular Open Source Web server. This tag should be used for general questions about Apache HTTPd.

Although there is large degree of commonality between the different versions in the 2.x branches, please consider using the Apache-2.2 or Apache-2.4 tags instead for more specific Apache HTTP Server related questions.

Documentation for all major versions is both comprehensive and has a high degree of accuracy.

Apache2: sites-enabled vs conf-enabled?

What is the difference between conf-enabled and sites-enabled (or conf-available and sites-available if you want to think of it that way)? When should a file go in one but not the other? Are they read into apache2 differently or at different times?
