Http request info
| 'HTTP response code | 200 |
| Download time | 0,547437 seconds |
| Filesize | 27544 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 | |
| Date: Fri, 25 May 2012 04:29:15 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. |
| Server: Apache/2 | The Server header contains information about the software used by the origin server to handle the request. The server used here is Apache/2 |
| Accept-Ranges: bytes | |
| Vary: Accept-Encoding | |
| Connection: close | 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 close |
| 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 |
| Content-Type: text/html; charset=utf-8 | 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; charset=utf-8 |
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
