 ## How to access arguments in a template
-Lets assume that your argument string for a specific post is something like this: `HIGHLIGHT|PREVIEW_IMG=foobar.png`. You can now access the entire (unparsed) argument string in templates by `$POST['ATTR']['ARGV']` (see template documentation for further information). This contains the unparsed argument string as he was written in the content editor. You also can access an parsed version of the arguments as key->value array with `$POST['ARGV']`:

 ## How this arguments can be used to do something special
-If you are a template developer, you can check within your templates if the argument `HIGHLIGHT` is present (arguments with no explicit value will be automatically set to `TRUE`). If true, you can highlight this post differently (if you have some "promo posts" or something: just check if this value is set and add an extra CSS class to your HTML markup which then will highlight your post).

 ## Conclusion
-The use cases of the arguments are practically unlimited. Please note that the templates of the `default` theme are not using any arguments provided in the argument field. It is up to you whether you implement this in your own template to do something special or not!

-This is the core language which will be used. A corresponding language file **must exists** within `core/language/`. Currently are only `en` and `de` supported. If you are a translator, please only use the original `en` language file for your translation and open a pull request on GitHub or send your language file via email to `code@nerdmind.de`!

 ## ETag configuration
-If this parameter is set to `TRUE`, the system will generate an `ETag` response header which includes a hash of the timestamps from the last created / edited items and sends him to the client. The client will cache this header and sends him with each further request in the request header back to the application. If the hash, which the appplication now creates again, is not the same as the one from the request header (which means that no new items have been published and no existing item have been edited), the application exit and returns the `304 Not Modified` response header to reduce server load and traffic.
+If `CORE.SEND_304` is set to `TRUE`, the application generates an `ETag` response header on each request which consists of a hash value based on the timestamps of the last created/edited items. The client will cache this information and sends it with the next request (inside the request header `If-None-Match`) back to the application.
+
+**Application sends `ETag` header:**  
+~~~
+ETag: "241d9ec9cb7526853698590929f06ae9-gzip"
+~~~
+
+**Client sends `If-None-Match` header on next request:**  
+~~~
+If-None-Match: "241d9ec9cb7526853698590929f06ae9-gzip"
+~~~
+
+The application now calculates again a hash value of the last created/edited items and compares it to the hash of the `If-None-Match` request header which was sent by the client. If these two hash values are **the same**, then obviously no new items have been created/edited since the last request by the client. Therefore, the application immediately exits and returns the `304 Not Modified` HTTP response status.

 ## Why database table prefixes are not supported
-The blogging application does not support the definition of a prefix for the database tables. This is because one database should only contain the data from one application (and if this is the case, prefixes are unnecessary). If multiple applications are sharing the same database and a security vulnerability is discovered in one of those applications, an attacker may be able to manipulate the data from the second application through the security vulnerability in the first application.
