adserve.inc in Advertisement 6
Same filename and directory in other branches
Configuration.
Copyright (c) 2005-2009. Jeremy Andrews <jeremy@tag1consulting.com>.
By default, adserve configuration happens dynamically as ads are served. However, it is possible to override dynamic settings with static defaults. Refer to the documentation/ADSERVE_CONFIGURATION.txt for details on adding adserve overrides to settings.php.
Note that the path to Drupal's root directory can not be overriden in settings.php as adserve needs this path to find settings.php in the first place. To hard code the path to Drupal's root directory, uncomment the following define statement, and set the correct path. This is not generally required. On a Unix server this path will be something like '/path/to/web'. On a Windows server this path will be something like 'D:\path\to\web'.

* 'TYPE' is replaced with the type of cache. For example, the included
* file cache lives in 'cache/file'.
*
* The ad_cache_TYPE.inc file must have a function named ad_cache_TYPE()
* which is used to display ads. It can optionally include a function
* titled ad_cache_TYPE_variables used to extract any necessary
* variables from the global $_GET array (this can also be used to override
* values that would normally be set from $_GET). Any functions used
* by this code without bootstrapping Drupal should also be in this file.
*
* The ad_cache_TYPE.module file should define the drupal _help() hook
* so the module can be enabled. It should also define the _adcacheapi()
* hook allowing for configuration and processing. Any functions used by
* this code after bootstrapping Drupal should also be in this module.
*
* Refer to cache/file/* for an implementation example.
