postback

I'm writing an intranet ASP.NET page using VB.NET. I've run into a particularly nasty problem dealing with handling file uploads. I'll do my best to explain the problem, and perhaps someone can help. My problem is almost a duplicate of this one , or this one , except (other than the filename) I don't care about sending the file to the server until the other data has been reviewed. Here's the situation: Joe Q. Dataentry inputs some data into several fields. The first 3 are drop down, and when he changes the selection, a postback event is fired that queries a database for valid entries for the

So I'm running a crawler on my server and I'm needing to execute javascript to gain access to some of the data on my target site (target being the one I want to crawl).

I am having a weird issue happening with outputcache. I have multiple user controls on a page, one of which is a login control. The page and the login control is NOT cached, but other user controls are cached with VaryByParam. Now all of this works along with caching when I click on to different pages.
