====== Why webapps is better than apache_config_* macros ======


===== 1. Unified structure. All configs are in /etc/webapps/$webapp =====
Admin is not confused, where's the config for app foo. 



===== 2. Simplier =====
No fancy rpm macro options, due layout being unified in front. 



===== 3. Can have multiple webapps configuration per .spec =====
The limitation is because symlink used is %{name} which you can't override in spec. This is not hard to overcome, but it still exists. 

In other words You can easily manage multiple instances of a given webapp, by simply adding another link to. 



===== 4. No confusing numbers =====
Using config load order is not needed anymore. Order in which webapps are loaded does not matter. 



===== 5. there's cli =====
There's a cli program called 'webapp' which you can use to view add and remove webapp links. 



===== 6. Separate apache configs =====
Apache 1.3 and apache 2.x can have different configs, so you can create different setup for different vhosts. This is not actually a limitation. 



===== 7. Free for other webservers =====
It is open to add any webserver. lighttpd has hooks but nobody has made any config. 



===== 8. You can have "modules" =====
You can have a webapp to have subwebapp. Say horde is the main package, and horde/imp is horde module. Then the webapp name for horde-imp is "horde/imp". The way the config symlinks are created module webapp configs are loaded before master. This allows you define /horde alias in main application and /horde/imp in sub application. It's transparent, you don't even have to think about that. 



<file># ls -log /etc/httpd/webapps.d/drupal*.conf
lrwxrwxrwx  /etc/httpd/webapps.d/drupal-tinymce.conf ->  ../../../etc/webapps/drupal/tinymce/httpd.conf
lrwxrwxrwx  /etc/httpd/webapps.d/drupal.conf -> ../../../etc/webapps/drupal/httpd.conf
</file>


===== 9. Webapps do not have to be rpm packages =====
In case you have application that's not rpm package, you can achieve similiar effect. As the program to register is available outside rpm macros.
