Question: Web Programming for Dynamic Site?

( Back )

Answer #1:

Javascript is code that runs in the browser.
It can do lots of things to make the site seem more responsive by avoiding the dreaded postback to a PHP or whatever page.

One of the many things it can do is an AJAX call. One of the many things you can do with an AJAX call is update stuff in the browser very quickly. Which is what it takes to make a site look 'very fast'.

But you still need something on the server to process things, the initial page request and the AJAX calls. That could be PHP, or some ASP.NET language, or JAVA, or...you have choices here.

Or you could go with something Flash/Flex based or even Silverlight. They give you much more control over what the user sees in the browser. But you still need something on the server to serve up the content.

Answer #2:

There are too many variables in this to be able to say "Do X Y and Z and the pics will be fast."

How fast is the users computer? How fast is their internet connection? How fast is your server(shouldn't be an issue but still)?

You have no control over any of this and these are what will determine how fast that image loads.An ocClick event only works so fast.
