Get Output through Pages

When a request is made for, say, an .aspx resource, the Web server passes it on to ASP.NET
for processing and receives the resulting HTML markup in return. The generated markup
comprises all the tags of a classic HTML page, including , , and

. The page
source is embedded in the HTTP response and tagged with a Multipurpose Internet Mail
Extensions (MIME) type to instruct the browser how to handle it. The browser looks at the
MIME type and decides what to do.

If the response contains an HTML page, the browser replaces the current contents entirely
with the new chunk of markup. While the request is being processed on the server, the “old”
page is frozen but still displayed to the client user. As soon as the “new” page is downloaded,
the browser clears the display and renders the page.
