Generate HTML file at runtime and send as email attachment

Random 404 using IIS
What would cause IIS to return a 404, only sometimes? If I hit a 404 on a page, I can simply hit refresh and it will come up. It’s reproducible. I’ve used fiddler to see what’s going on and I don’t see anything off. I’ve setup IIS tracing but again, I don’t see what exactly the issue would be, the file exists and the 404 only occurs sometimes. By sometimes I mean if I navigated to a page and got a 404 I could refresh and it would come up but other times I could navigate to that page and it would not 404. It isn’t limited to any one page or condition.

In the code that renders the report, it’s DataSource is bound to a List(Of ClassA) objects defined in a custom assembly. This seems to work for the most part. My problem is that I can’t seem to handle the situation where a nested object is null. For example, given ClassA and ClassB (the nested object) defined as follows:
