HTTP Browser Header Checker
Introduction to HTTP browser headersWhen making HTTP
requests for pages over the Internet, a browser sends a number of
information header lines to the webserver which will serve that request.
Those HTTP information headers do not only contain information about the
page that has to be retrieved, but also contain configuration and system
information of the browser and of the computer the browser is running on.
This information can be used by the webserver to serve the best matching
content to the client.
Most Internet users—and also many website builders—are not aware of
this extra set of information which accompagnies every request. Proper use
of these HTTP headers by webservers can however improve the user
experience significantly by matching the response as close as possible to
the user and browser preferences. One example is serving webpages in the
primary language of the browser. Another example is serving light weight
pages when a mobile device is connecting, or send images in the format
best processed by that particular browser or output device.

Most common HTTP browser headersBrowsers send a variety
of HTTP headers. This list contains the most common HTTP headers you will
see coming from regular browsers and bots like the crawlers from the major
search engines.
Most common HTTP headers sent by browsers
| HTTP Header |
Description |
| Accept |
This HTTP header contains the MIME types which are
accepted by the browser. This can be a list of specific MIME types,
but the list may also contains wildcards. The entries in the list
are separated by commas. Priority values can be assigned to each
MIME type by adding a semicolon followed by a q=val
parameter. The priority value val ranges from
0.0 to 1.0 where higher values represent higher
priority. In this way the browser can request specific content
types, for example JPG files over PNG files if both are available on
the server.
Example:
text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
|
| Accept-Language |
The browser sends preferred language information in
this HTTP header. The content of the HTTP header is a list of one of
more languages. Each language is represented by a two character code
like en for English, or a five character code like
en-US for American English if a subset of a
specific language is requested. Entries in the list are separated by
commas. A priority value can be assigned with each language by
adding a semicolon followed by a q=val setting. The
priority value val may range from 0.0 to
1.0, where 1.0 is the highest priority and 0.0
the lowest.
Example: en,en-us;q=0.7,nl;q=0.3 |
