Can onExtensionAfterInstall trigger cache updates automatically

1. Clearing Cache:
- The `onExtensionAfterInstall` event can be used to clear the cache after an extension is installed. This ensures that any changes made by the extension are reflected immediately.

2. Cache Configuration:
- The event can also be used to configure caching settings for the newly installed extension. This includes enabling or disabling caching, setting the cache lifetime, and selecting a cache handler.

3. Cache Handler:
- The `onExtensionAfterInstall` event can be used to set up a cache handler for the extension. This involves selecting a cache handler, such as Cache_Lite, and configuring its settings to optimize caching for the extension.

4. Browser Caching:
- Additionally, the event can be used to configure browser caching settings for the extension. This involves enabling or disabling browser caching and setting the cache expiration time to control how long browsers cache the extension's content.

Here is an example of how the `onExtensionAfterInstall` event can be used to clear the cache and configure caching settings:

php
function onExtensionAfterInstall($installer, $eid)
{
    // Clear the cache
    $cache = JFactory::getCache();
    $cache->clean();

    // Configure caching settings
    $config = JFactory::getConfig();
    $config->set('caching', 1); // Enable caching
    $config->set('cache_handler', 'file'); // Set cache handler to file
    $config->set('cachetime', 15); // Set cache lifetime to 15 minutes
}

In this example, the `onExtensionAfterInstall` event is used to clear the cache and configure caching settings, including enabling caching, setting the cache handler to file, and setting the cache lifetime to 15 minutes.

This ensures that the cache is updated automatically after an extension is installed, reflecting any changes made by the extension.
