The Google analytics surrogate needs to catch more, set noscript.surrogate.ga.replacement to

Code: Select all

(function(){var _0=function(){return _0;};_0.__noSuchMethod__=_0;with(window)urchinTracker=_0,_gaq={__noSuchMethod__:_0,push:_0,_link:function(h){if(h)location.href=h},_linkByPost:function(){return true},_getLinkerUrl:function(u){return u},_trackEvent:_0},_gat={_getTracker:function(){return _gaq}}})()

Perhaps it should be updated to use proxies, Giorgio?

Unfortunately we're still supporting Fx 3.x, which has no proxies.

Of course NS 3.x, when it gets its Surrogates porting, will take advantage of proxies everywhere.

Please check latest development build 2.1.2.7rc3, thanks.

Thanks. This works.

_gat needs another method, _createTracker, I guess it might as well be __noSuchMethod__.

Code: Select all

(function(){var _0=function(){return _0;};_0.__noSuchMethod__=_0;with(window)urchinTracker=_0,_gaq={__noSuchMethod__:_0,push:_0,_link:function(h){if(h)location.href=h},_linkByPost:function(){return true},_getLinkerUrl:function(u){return u},_trackEvent:_0},_gat={__noSuchMethod__:function(){return _gaq}}})()
