Hi,

The path to the data file needs to be in another element. Change back what the devicesFile was before (probably ~/App_Data/device.dat") deviceFile isn't for data, it is for keeping a record of previous requests for redirection purposes, particularly in multi server environments.

Your fiftyOne section should look something like this:
<fiftyOne>
   <redirect>
   <!-- None of this needs changing-->
   </redirect>
 
   <log>
   <!-- None of this needs changing-->
   </log>
 
    <detection name="data" binaryFilePath="~/App_Data/51Degrees.mobi-Lite-2012.01.18.dat" enabled="true" />
</fiftyOne>

Thanks,
Tom

Thanks for the reply Tom.
Same story.

I have specified the path as follows:
<detection binaryFilePath="~/App_Data/51Degrees.mobi-Lite-2012.01.18.dat" />

Just so I understand the process: is 51mobi detection kicked off when I initiate: Browser.IsMobileDevice

I guess these are the lines where are the action is:

Debug - Request for 'http://sitename.electricocean.co/' with handler type 'System.Web.Mvc.MvcHandler' and current page '' is not a restricted page for redirect.

Just a quick note to report status update. Seems the Facebook like user agent is not part of the 51Degrees.mobi-Lite-2012.01.18.dat file so Facebook is redirected to your mobi site when it scrapes your page. 

I have a custom view engine and the mobileHomePageUrl attribute in the redirect config element was causing problems for me and had to remove it to get the view engine working.

I have resorted to a manual hack by checking as follows:
private static bool _IsMobileDevice ()
        {
            var isMobileDevice = HttpContext.Current.Request.Browser.IsMobileDevice;
            //HACK: issue with Facebook scraper viewing the site as MOBI site.
            if (HttpContext.Current.Request.UserAgent != null)
            {
                if (HttpContext.Current.Request.UserAgent.Contains("facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_u...)"))
                {
                    Log("FB UserAgent");
                    isMobileDevice = false;
                }
            }
            return isMobileDevice;
        }

Hi,

Sorry for the confusion. We have just identified a discrepancy between how the Lite and Premium data is created so it appears the Facebook crawlers did not make it into the Lite data when they should've done.

We'll be correcting this in an update very soon.
Thanks,
Tom
