 User agent - Wikipedia, the free encyclopedia
One result of user agent spoofing is that the usage share of Internet Explorer, the user agent browsers typically spoof, is probably overestimated, and the usage share of all other browsers may be underestimated.
A user agent is the client application used with a particular network protocol; the phrase is most commonly used in reference to those which access the World Wide Web.
When Internet users visit a web site, a text string is generally sent to identify the user agent to the server.

 User agent refs
Conforming user agents may consider the value of "text-transform" to be "none" for characters that are not from the ISO Latin-1 repertoire and for elements in languages for which the transformation is different from that specified by the case-conversion tables of Unicode or ISO 10646.
The user agent may address this by causing the next side-float or normal block-area to "clear" one of the relevant side-floats, as described in the "clear" property description, so the intrusion adjustment is sufficiently reduced.
User agents must map names to values in a way that preserves visual order; a face mapped to a value must not be lighter than faces mapped to lower values.

 Software agent - Wikipedia, the free encyclopedia
In computer science, a software agent is an abstraction, a mental model that describes software that acts for a user or other program in a relationship of agency
For example, the agent may detect a decline in the construction industry for an economy; based on this relayed information construction companies will be able to make intelligent decisions regarding the hiring/firing of employees or the purchase/lease of equipment in order to best suit their firm.
Since agents are well suited to include their required resources in their description, they can be designed to be very loosely coupled and it becomes easy to have them executed as independent threads and on distributed processors.

 HTTP/1.1: Header Field Definitions
Quality factors allow the user or user agent to indicate the relative degree of preference for that media-range, using the qvalue scale from 0 to 1 (section 3.9).

Sometimes a user agent might want or need to insist that a cache revalidate its cache entry with the origin server (and not just with the next cache along the path to the origin server), or to reload its cache entry from the origin server.

 RFC 1524 (rfc1524) - A User Agent Configuration Mechanism For Multimedia M
Crucial to this scheme, however, is that all of the user agents agree on a common representation and source for the configuration file.
One approach to this transition is to modify diverse sets of mail reading user agents so that, when they need to display mail of an unfamiliar (non-text) type, they consult an external file for information on how to display that file.
Location of Configuration Information Each user agent must clearly obtain the configuration information from a common location, if the same information is to be used to configure all user agents.

 Dan's Web Tips: Brand-X Browsers -- User Agent Strings
So it seems like we're stuck for the indefinite future with user agent strings that get further and further away from honestly describing the browser name and version they represent, and contain increasing amounts of fossilized deadwood that can't be removed because some site, somewhere, allegedly depends on its presence.
Whenever anyone gives statistics purporting to identify what percentage of users are using which browsers, this is (if it's not just somebody's wild guess) probably taken from analysis of the user agent identifiers of visitors to a Web site.
Some info on user agent strings (with some misguided comments; the author is critical of browsers whose UA strings don't include "Mozilla or MSIE compatibility numbers", apparently thinking that these strings ought to mimic other browsers instead of honestly identifying what the browser is.)

 The Old Joel on Software Forum - Browser "User Agent"
If you do consistently change the User Agent though you may not be getting the best out of the browser since a page may sniff on the basis of the User Agent alone and assume your browser can't do what it actually can.
One of the reasons to change a Browser's user agent string is because some sites will not allow access to non-IE browsers even when a Gecko or KHTML based browser will read the content just fine.
Sites like banks require IE as a user agent because it's the only browser that they bothered to test on and they have pretty strict confidentiality and security requirements.
