Important Notice

This plugin has only been used on a very few simple blogs. Therefore, it should be considered experimental.

I do not recommend running this plugin in production, unless you have previously thoroughly tested it with your specific configuration, especially in complex WordPress installations. In any case, by running this plugin in production, you are on your own.

Please note that I no longer provide any information about the compatibility of this plugin with recent WordPress releases. Please, test it yourself, so as to be sure it works well with your configuration.

Due to lack of free time, there are no plans to work on this plugin in the near future. If it does not work as expected for you, I strongly suggest to look for other plugins in the WordPress Plugin Repository.

Before reading any further

Before reading any further or using this plugin on your WordPress platforms, please make sure you have thoroughly studied the FAQ. This plugin might not be what you think it is. Also, this plugin might not be the right plugin for you.

Notice regarding the functionality of 2.X.X releases

In Add-Headers releases older than 2.0.0 caching was enabled by default. This resulted in several users, who didn't have the required knowledge about HTTP caching, assuming that the plugin would somehow auto-configure itself according to their web sites' special needs. So, since 2.0.0, no page is allowed to be cached by default and the configuration of the plugin has become mandatory in order to make the dynamic pages cacheable.
