Well I am going to try the redirects... but to further describe the application, I am writing some pages that will calculate concentrations of various chemicals to make a particular electrolyte that the user inputs. So the calculations for Electrolyte A are different than that for Electrolyte B. I was going to have a common parameter page, and use different includes that do the specific calculations. The includes contain vbscript, although I could use Jscript instead, as well as ASP. How does the content make a difference, however, if the includes are processed before the ASP code?
