I do not mean the parts of the user-agent string in that field in the request header. I mean the other information that servers can get about the browser with javascript code to do detailed browser-sniffing. If you choose Edit User Agents from the menu for User-agent Switcher and add a new user-agent, you will see that there are 5 items that are filled in from your browser automatically to begin. The first is the user-agent string, but the others are App Code Name, App Name, App Version, and Platform. It is the last four that are missing from the list of fake user-agents that you get with the file that is made available for download. I wanted to fill in those blanks for other browsers to make more convincing fakes, so I need that information.

If the server checks for capabilities then faking such navigator properties won't help you.

The appCodeName and appVersion also show as part of the user agent (Mozilla/5.0 (Macintosh; -> 5.0 (Macintosh), so you can inspect the various user agents and extract this data. In Firefox the AppName is always Netscape and the AppVersion 5.0 plus a platform code

Your Safari user agent:

• User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8)

appCodeName: Mozilla appName: Netscape appVersion: 5.0 (Macintosh) platform: Intel Mac OS X 10_6_8

On Linux, you usually see Mozilla/5.0 (X11; Linux i686; ) or Mozilla/5.0 (X11; Linux x86_64; ) So appVersion: 5.0 (X11) and platform : Linux i686 or Linux x86_64

Thanks for the pages. I have bookmarked them for reference. Not quite what I need, but informative.

As far as the Safari information goes, actually, the info you gave is not quite right.

• userAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/534.59.10 (KHTML, like Gecko) Version/5.1.9 Safari/534.59.10
• appCodeName and appName are correct
• appVersion: 5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/534.59.10 (KHTML, like Gecko) Version/5.1.9 Safari/534.59.10
• platform: MacIntel

For SeaMonkey, that info is:

• userAgent = Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:33.0) Gecko/20100101 Firefox/33.0 SeaMonkey/2.30
• appCodeName and appName are the same
• appVersion = 5.0 (Macintosh)
• platform = MacIntel

For Opera using a Presto rendering engine:

• userAgent: Opera/9.80 (Macintosh; Intel Mac OS X 10.6.8; U; en) Presto/2.10.229 Version/11.62
• appCodeName: Mozilla
• appName: Opera
• appVersion: 9.80 (Macintosh; Intel Mac OS X 10.6.8; U; en)
• platform: MacIntel

The format for the platform differs among operating systems. For Windows 32 bit, the platform is Win32, and for Windows 64 bit, the platform is Win64. For a Mac with a Motorola CPU, the platform is MacPPC. The exact format used for version differs with the browser used. My problem is that I do not know all of them. The examples I am giving are from browsers that I have and can test with testing sites. A good testing site is here: http://dev.jeffersonscher.com/jstest.asp
