'What is the standard format for a browser's User-Agent string?
Is there an RFC, official standard, or template for creating a User Agent string? The iphone's user-agent string seems strange...
Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_1_2 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7D11 Safari/528.16
Solution 1:[1]
This is specified in RFC 1945 in the section on Request Headers. It is not a very standardized format, though, and user agents tend to put whatever they want in there.
Solution 2:[2]
Yes, see: mozilla website, but as it was mentioned before. Basically you can put whatever you want there. For statistical/analytical purposes, the most important thing is, that every browser/os should have this standardized for itself.
