Identifies the browser for this session.
Identifies as much as possible of the browser name and version, OS name and version, and the renderer name and version. The renderer is then used to determine which capabilites are supported.
Located in Program_Root/browser.php (line 98)
User-agent string received in HTTP request.
Lowercase version of the user agent string.
Resolve the domain name of the browser.
Build date of the browser, if built with Gecko.
Gecko is the mozilla browser technology. Conforming user agent strings include the build date of the Gecko component. (Can be empty)
Calculated system name.
The most likely operating system derived from the user agent string.
Return actual ip address of browser (resolves proxies).
Does the browser use this renderer or run on this operating system?.
See the browser renderer/OS constants.
Name of the browser.
Not necessarily the same as the renderer name. AOL uses the IE engine or the Gecko engine, depending on version. MSN uses the IE engine.
Identifies the technology used by this browser.
This is often different than the name, since many browsers employ embedded renderers like Gecko, or are rebranded like Opera Composer browsers.
Identifies the version of the technology used by this browser.
This is the number used internall to identify whether a feature is supported.
Is the requested functionality supported?.
See the browser functionality constants.
Fully formatted operating system id.
Returns as much information about the operating system as possible.
Specific name of the operating system.
Operating system version.
This is specific, like Windows NT 5.1 (Windows 2000) will return 5.1, not 2000.
Version of the browser.
Not necessarily the same as the renderer version. Largely useless identifier for determining feature support, but nice to use when showing a user which browser they are running. e.g. displaying 'MSN 7.0' instead of 'IE 5.5sp1'.
Determine browser name, technology, operating system and versions.
Called from the attribute access functions to make sure the user agent has been parsed.
A list of ids known to be spurious or system ids.
The algorithm always uses the last non-ignored id as the browser id; this list determines which ids are ignored.
A mapping of user agent fragments to platform ids.
The platform id is a nicely formatted, standardized name for the operating system. This array maps the different user agent platform ids onto these standard ones. (e.g. 'nt 4' and 'nt4' both map onto 'Windows NT 4.x').
A list of the known rendering technologies.
Each id maps to the rendering technology to record (retrieved later with the 'is' function), a pretty-printed name for the renderer and a level. The level determines which renderers override others if more than one renderer is specified. That is, almost every user-agent on the planet returns mozilla x.x, but that renderer declaration is overridden by any other one that comes along. IE is the next weakest because many user agents spoof as IE as well. If either or both of these are specified, they are recorded, but if any other renderer is specified, that one is used instead.
A list of systems known to provide version info in the user agent.
