www.knmi.nl server info

www.knmi.nl server info

A good server setup can make a huge difference for website performance and may even enhance the ratings in the search engine results since page speed has become an issue.

Http request info

'HTTP response code 200
Download time 0,122644 seconds
Filesize 28082 bytes

Server headers

Server headers are the response the server sends before the actual content. A correct server setup can speed up a site and free up server resources. Make sure that all headers are set correct. For example dont cache dynamic content and dont close connections unless there is a good reason.

HTTP/1.1 200 OK
Server: Apache The Server header contains information about the software used by the origin server to handle the request. The server used here is Apache
Keep-Alive: timeout=15, max=100
Content-Type: text/html The Content-Type entity-header field indicates the media type of the entity-body sent to the recipient or, in the case of the HEAD method, the media type that would have been sent had the request been a GET. . The value is text/html
Accept-Ranges: bytes
Connection: Keep-Alive The Connection general-header field allows the sender to specify options that are desired for that particular connection. Common values are keep-alive and close. Keep alive means the connection to the server should stay open for re-use. Usually this means a speed advantage for a website since the connection can be reused to fetch images, javascript, css etc. The value is Keep-Alive
Date: Fri, 25 May 2012 20:51:11 GMT The Date header represents the time when the message was generated, regardless of caching that happened since. It is used by caches as input to expiration calculations, and to detect clock drift.
Age: 20 The Age header conveys the sender's estimate of the amount of time since the response (or its validation) was generated at the origin server. The age of this file is 20 seconds
Content-Length: 28082 The Content-Length header indicates the size of the body, in number of bytes. In responses to the HEAD method, it indicates the size of the body that would have been sent had the request been a GET. If Content-Length is incorrect, persistent connections will not work, and caches may not store the response (since they can't be sure if they have the whole response). The content length is 28082 bytes

Server location

Server location is important because a server that is located near the customer will serve pages faster then a server located far away
