Well its like anything else, its personal preference and who your talking too, this is
standard
coding pratice offered by our development firm, and I have continued the practice. To
be honest,
you should almost never have logic code contained on the same page as your
presentation code. I
have never run into a problem with people saying that they are seeing lags or such,
but then again
that could just be because the code that is on those pages is compact. Most ASP
people and JSP I
know do it either this way for most of their code, there is some minor for loops or if
statments
in the HTML code, either that or the have functions and class stored elsewhere.
