So the problem is half the app is written in classic asp and half is in asp.net. There's a PDF file (in memory) that is generated by classic asp code that I need to share with the .NET half. I thought of saving the PDF to the FS or DB, which I am pretty sure most of you wouldn't recommend because it would need to go through a very slow p...

When working with HTTP modules, has anyone noticed that the final two events in the pipeline -- PreSendRequestHeaders and PreSendRequestContent -- don't always run?

We're trying to figure out how to fix a bug found in 3rd party IV&V testing, which we can't recreate in our internal test environment. We've determined that the bug is caused by a URL value being inadvertently set to an empty string ("") before attempting to redirect to it. Hence, we're trying to execute Response.Redirect("").

Developers and management tell me that they want to move away from using asp.net ajax because it is big and cumbersome.

Is there a good post somewhere outlining...
I'm looking more towards CMS's as I'd like my clients to be able to be as self sufficient as possible. Anyhow, I'm just starting to evaluate and will update this with my conclusions. However, since I'm starting with evaluating Umbraco first, I'd like to get a consensus. I have no preference for C# or Vb.Net. so I'm open to either. ...

Something like: <asp:Parameter Name="AppVal" Type="Int32" DefaultValue="<% Application['MyVal'] %>...
