Bug: I've got an ASP.NET web application that occasionally sets identical cookie keys for ".www.mydomain.com" and "www.mydomain.com".

When 2 cookies have the same key and are sent up f...

Setting the selected printer to Adobe PDF is not an option. Learn to programmatically create PDFs from scratch? Is there a way to render it in some browser control, t...
Without resorting to using an ActiveX or some other kind of client side coding: Is it possible to determine if a visitor to a website arrived to a page via his bookmarks or the home page? Personally I think its impossible, but I would like to be sure or proven wrong. The way I am doing something like this at the moment is: Request.Ur...

How do I benchmark the performance of my web applications? Is there a way to find out the bottlenecks in a web application? EDIT: I am not asking about any front end tweaks like images, css etc. What I want to know is how to profile the back end of the application so that I will know which methods/queries to modify to increase the perf...

Hi, I'm trying to set the value of a hiddenfield control in an AJAX initialize request handler. However on the server the hidden field control always contains the value for the previous postback.
