UFrame: goodness of UpdatePanel and IFRAME combined
UFrame combines the goodness of UpdatePanel and IFRAME in a cross browser and cross platform solution. It allows a DIV to behave like an IFRAME loading content from any page either static or dynamic. It can load pages having both inline and external Javascript and CSS, just like an IFRAME. But unlike IFRAME, it loads the content within the main document and you can put any number of UFrame on your page without slowing down the browser. It supports ASP.NET postback nicely and you can have DataGrid or any other complex ASP.NET control within a UFrame. UFrame works perfectly with ASP.NET MVC making it an replacement for UpdatePanel. Best of all, UFrame is implemented 100% in Javascript making it a cross platform solution. As a result, you can use UFrame on ASP.NET, PHP, JSP or any other platform.

Fast ASP.NET web page loading by downloading multiple javascripts in batch
A web page can load a lot faster and feel faster if the javascripts on the page can be loaded after the visible content has been loaded and multiple javascripts can be batched into one download. Browsers download one external script at a time and sometimes pause rendering while a script is being downloaded and executed. This makes web pages load and render slow when there are multiple javascripts on the page. For every javascript reference, browser stops downloading and processing of any other content on the page and some browsers (like IE6) pause rendering while it processes the javascript. This gives a slow loading experience and the web page kind of gets 'stuck' frequently. As a result, a web page can only load fast when there are small number of external scripts on the page and the scripts are loaded after the visible content of the page has loaded.
