#923 IE11 detection not always working

[Julien Cyr]

Detection of IE11 as been added in awtats 7.3. It is working, but the regex is not catching all cases. The regex is detecting "Trident/7.\d; rv:\d.\d.". But, there is multiple token between "trident" and "rv" that can occur.

For example, if IE11 is on a touch device (tablet, AiO/laptop with touchscreen, etc), there is a "TOUCH;" token.

Some examples of UA string not catched by the regex:
Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; TNJB; rv:11.0) like Gecko
Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; ASJB; ASJB; MAAU; rv:11.0) like Gecko
Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; Touch; MAARJS; rv:11.0) like Gecko

All those cases go to "Mozilla" browser...

I'm not sure about how it should be managed since the tokens are not defined. Maybe something like :

my $regvermsie11      = qr/trident\/7\.\d*\;[^()]*rv:([\d\.]*)/i;

Probably a better one will be:

my $regvermsie11      = qr/trident\/7\.\d*\;([+_ ]|)([\w\.]+\;([+_ ]|))*rv:([\d\.]*)/i;

I added the dot with the \w because I think it can be a token about .NET framework version. (ex.: .NET4.0C)

[Laurent Destailleur (Eldy)]

I think replacing
my $regvermsie11 = qr/trident\/7.\d\;([+_ ]|)rv:([\d.])/i;
into
my $regvermsie11 = qr/trident\/7.\d\;([a-zA-Z;+_ ]+|)rv:([\d.])/i;

Is this ok for you ?

Probably a better one will be:

my $regvermsie11      = qr/trident\/7\.\d*\;([+_ ]|)(\w+\;([+_

]|))rv:([\d.])/i;

It should be good. It will not catch token like ".NET4.0C", but I was not able to find this token on a IE11 UA string in my last two days of log (about 1GB). So maybe they remove that token for IE11. I didn't find anything in Microsoft documentation, except they suggest to detect only with the Trident version. I don't think it's a good idea since there is other browser (like Maxthon) that can use Trident.

Upgraded to AWStats 7.3 and can't see any IE 10 or IE 11 browser detections in our intranet environment. Only Msie 9.0 and Msie 7.0. We are running Windows Server 2008 R2 32bit, IIS 7.5 and Perl 5.18. Is there a fix available?

[Laurent Destailleur (Eldy)]

Fix should be available with 7.4
