ASP.NET pages never stop loading <p>We have a problem with many of our website written C# ASP.NET. The problem is that often a C# page will never fully load from the server. The page content itself load fine but Images but more annoying Scripts (Javascript) seam to hang and never come down and depending on the content it might lock up the page on Ajax Postback.</p> <p>This problem is not limited to a single server as it happens on development machines as well as pre production and production servers.</p> <p>The development machine are just using the inbuilt VS IIS Instance.</p> <p>All pages that have this problem use ASP.NET Update Panels with varying versions of AJAX Toolkit.</p> <p>Thanks</p>
