Until OutSystems Platform 5.1, we were setting some browser capabilities definitions in the .NET machine.config files. This allowed to provide support for old mobile phones, but it was lacking support for some recent browsers such as Internet Explorer 10.
What are browser capabilities?
Different browsers, and different versions of the same browser, support different features. ASP.NET server controls will automatically determine the browser that has requested the page and render the appropriate markup for that browser.
One way to create custom browser capabilities definitions is by changing the <browserCaps> element in .NET machine.config files, although it has been deprecated in the .NET Framework version 2.0.
Why we want to remove browser capabilities?
Until the OutSystems Platform version 5.1, we were setting some browser capabilities definitions that are leading to wrong detection of browser capabilities for some recent browsers like IE10.
There are two choices to overcome this problem:
As the .NET Framework already supports the most used browsers (and a lot of others that you probably never heard about) we've decided to remove all the settings in the <browserCaps> element.
Apply a Microsoft hotfix regarding .Net browser definition files
If you don't have the .NET Framework up-to-date in your servers, the previous procedure might not be enough to overcome this problem.
So, if after fixing your browser capabilities the problem persists, we recommend you to take a look at this blog post that details an issue when using IE10 with a Windows Server where the .NET browser definition files have not been updated to recognize this new browser version.
We have seen some servers where this hotfix was necessary to help fixing the problems that were experienced when using IE10. A lot of Windows Server installations should have this correction already applied by the automatic Windows Updates.
Nevertheless, we recommend you check if these hotfixes are applied:
What about custom browser capabilities?
If you have customized your browser capabilities settings and you can’t simply remove it, please take a look in the procedure below.
This procedure describes how to identify and fix your settings to support Internet Explorer 10. You must apply this procedure to all the front-ends in your OutSystems installation – i.e. all machines where you have the Agile Platform Server installed.
If you installed the Agile Platform for the first time in version 6.0+, and you have not customized the <browserCaps> element in machine.config to support special browsers, you can skip this step.
Otherwise follow the steps below to validate if you are correctly identifying IE10:
