Symptoms
You experience out of memory exception errors on a Web server that has Microsoft ASP.NET 1.1 installed. ASP.NET 1.1 is installed as part of the Microsoft .NET Framework 1.1 and the Microsoft .NET Framework 1.1 Service Pack 1 (SP1).
Resolution
This problem occurs because the MobileCapabilities object does not expire from the cache as expected. You can use an instance of the MobileCapabilities object to read the capabilities of the requesting browser and device.
