6 Replies and 148 Views Content-Type set to application/xhtml xml for IE 11  148  6 Started by  Don Adams We recently upgraded to v3.2.22.2 from When requesting a .Net aspx page in IE 11, the Content-Type is set to application/xhtmlxml rather than text/html. This same page request works fine in Chrome, Firefox, and Edge. The only thing that has changed was the upgrade to v3.2.22.2. We are using the 51Degrees-LiteV3.2.dat data file. In the config file, the only sections that are enabled are the log and detection sections. The redirect and imageOptimisation sections are commented out. ...

2 Replies and 323 Views Latest .dat file is Nov 2018 (7 mo old) - not Monthly?  323  2 Started by  rmariotti01 I just updated my Nuget packages to v3.2.22.1 (mobi-core), v3.2.18.11 (mobi-data) and v3.2.21.1 (mobi-web), but these latest packages were updated 7 months ago 'Date published 11/13/18'. Is this the proper way to manually update my Lite 51Degrees.dat file (via nuget) Or is there a download .dat somewhere that didn't show in my research Thanks for the guidance! R. Mariotti

8 Replies and 1762 Views Azure - WinIOError    1762  8 Started by  Marshalls UK Hi We have some MVC sites hosted in Azure and several times over the last few months the sites have thrown exceptions for specific devices. For example, the latest issue meant that the site was visible for desktop and iOS browsers but when viewing on an Android device the site never loads and an ASP.NET error page is displayed (error below). This bypasses the custom error pages we have set up, so the customer sees the full error. Restarting the web app resolves the issue. We are using 5...

2 Replies and 1091 Views Source Control and .dat file  1091  2 Started by  Zach Wenta Currently, we have the 51Degrees.mobi-Premium.dat file stored in our source control. It weighs in at 212mb. When we are running the project from our dev machines, we on occasion get updates to this file and then that new version gets merged into Source Control. Ideally, I'd like to not keep this in my SC and instead have the first time we load the site, get the latest version of the .DAT file. Same for my production servers. Is there a way to keep this out of SC and instead pull the fil...

1 Replies and 944 Views (Solved) Production and test servers revisited    944  1 Started by  Bill Hebb Hi: Running 51mobi lite on IIS. Worked very fine on development box, pushed up to the production server and nothing works. Set the config to debug, but the log.txt file never changes - but it does on the development server. Also never generates a tmp file, but does on the development server. Sounds like a rights issue to me, but to whom do I grant the write right - if that is what I need to do... Thanks in advance, Bill

1 Replies and 1240 Views (Closed) Potential for use from SQL Server against existing logged user agent strings?    1240  1 Started by  MandyShaw Need a device detection solution to run from SQL Server 2008 R2 against logged user agent strings stored in the database. I am thinking that the 51Degrees .Net library a CLR stored procedure might do the job. Can anyone advise whether you think this feasible please. Obviously I am assuming that the library provides a low level API to parse an existing user agent - I don't need any of the redirection etc. Thanks.
