问题 I have an asp.net web page with a ton of code that is handled in the Page-Load event of the page. I also have a dropdown box on the page that should reload the page with a new value, but I would like to get this new value before I process the entire Page-Load code. I am trying to get my head around ASP.NET page lifecycle. Should I move the Page-Load code to a later event or is there a way to get the value of the dropdown list value before the the Page-Load event begins? TIA 回答1: I would use

问题 I am building a simple tool that tracks and increases the number of visits of a website. It's something simple as: When the server receives a GET request, it will increase the counter in database for that website by 1. However, I am running to a bit problem with Google Chrome's pre-render engine ("Predict network actions to improve page load performance"). The website is www.domain.com, and as soon as you type the domain name www.domain.com into the browser's address bar (without pressing
