www.chemieforum.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.

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/1.1 302 Found
Server: cloudflare-nginx The Server header contains information about the software used by the origin server to handle the request. The server used here is cloudflare-nginx
Date: Fri, 25 May 2012 10:55:06 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.
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
Transfer-Encoding: chunked The Transfer-Encoding header indicates what (if any) type of transformation has been applied to the message body. This differs from Content-Encoding in that transfer-codings are a property of the message, not of the representation; i.e., it will be removed by the next "hop", whereas content-codings are end-to-end. The most commonly used transfer-coding is chunked, which allows persistent connections to be used without knowing the entire body's length. The value is chunked
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
X-Powered-By: PHP/5.2.17 The non-standard X-Powered-By header is used by applications running behind a web server to advertise their specific technology. A few examples could be php and asp. The technology used here is PHP/5.2.17
Location: http://www.chemieforum.nl/forum/index.php?act=home

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

www.chemieforum.nl javascript

www.chemieforum.nl javascript info

Javascript is a scripting language to enable Web authors to design interactive sites. On this page we found 4 external javascripts and 4 internal javascripts on www.chemieforum.nl

Javascripts in the head of the page

The following js files were found on this page:

http://www.wetenschapsforum.nl/public/min/index.php?ipbv=32006&g=js
http://www.wetenschapsforum.nl/public/min/index.php?ipbv=32006&charset=iso-8859-1&f=public/js/ipb.js,cache/lang_cache/2/ipb.lang.js,public/js/ips.hovercard.js,public/js/ips.quickpm.js,public/js/ips.forums.js
http://www.chemieforum.nl/graph/graph.js
http://pagead2.googlesyndication.com/pagead/show_ads.js

seo tip: put all javascript in one file r-domain advises to combine all javascript to one javascript. Javascripts normally are loaded before the page is displayed. Adding multiple javascript to your page can seriously slow down your website.

www.chemieforum.nl inline javascript info

seo tip: avoid inline javascript Usually it makes sense to keep the amount of inline javascript to a minimun since this kind of javascript is not cachable. Usually the faster alternative is to put these snippets in an external script.

The following inline javascript snippets were found on this page:
