What Is An ASPX File Extension?

 
There seems to be two basic file
formats for Microsoft's Active
Server Pages. There's .asp
and there is .aspx.

What's the difference?

Here's a web page that describes
the .aspx extension:

What is an ASPX File?

As the web page above says, .aspx
is for a ASP.NET application. That's
the new form of ASP. The old form
was just simply called ASP.

I suppose the lesson here is that sometimes
a new file format also gets a new face. In
this case, the new file format is the one
with the .aspx extension.

I'm using the term file format very
very loosely here. Neither one of these
file extensions is really a file format.
Rather, it is a file that contains programming
code for specific programming languages
offered by Microsoft.

So, comparing a .aspx file to a
.asp file, a .aspx file is
more likely to have the most up-to-date
code. Not a guarantee, just a probability.

I'm not an expert on Microsoft products.
Just trying to learn myself.

To write more about this, I'd probably
have to immerse myself in the Microsoft
programming culture. In all probability,
they have their own way of expressing
themselves in the Microsoft world. In
the Microsoft programming culture, they
also probably have their own generally
accepted solutions to common problems.

That's how programming cultures work.
