SetUserAgentString not affecting browser user agent - Android Developers. I wouldn't necessarily advise replacing the user agent string completely, as other pieces in the chain might become confused. it's also possible that at request time WebKit is rejecting your string and sending the default one. if i'm reading it correctly, the standard for user agent strings specifies space-separated tokens. hence i get the current user agent string, then append a space and my keyword. my rails app picks up the key and does the right thing. works fine for me!
