Object reference not set to an instance of an object
<p>I am facing a peculiar problem with an asp.net 2.0 application(C# code behind) which has been running smoothly for last 3 years or so.The thing is that I have one custom object named "Horse" which becomes null at a particular line where I check for its nullability though there is seemingly no reason for its becoming null at this line.Interestingly when I spit the content of this object using Response.Write just before the line where I am getting the null reference exception, it shows the content of the "horse" object to the browser.</p>

<p>More interesting thing is that if I access the page from IE 6.0 and IE 7.0,I don't get the exception at all.But if I use IE 8.0,then I get this exception.</p>

<p>Can anyone please tell me reason and solution for this issue?
Thanks in advance!
