Apache status code

Apache作为最常见的web 服务器，有时常常察看其日志文件来判断一些情况。下面是常见的一些状态代码。
If you see a lot of 304 status codes it means that users are bookmarking and revisiting your site.

If you have a most wanted response by your users, you can study the path that each user took to reach that response.

For example if your mwr is for a user to download a file, you would study the path each took before downloading and look for a pattern.

This could help you to enhance the content of the pages that were accessed and eliminate the unused.
