What should I use PHP, ISAPI, and/or ASP?

I don't know if this is the best place to post this thread but I looked for general and sever-side web programing forum here at codeguru.com but saw none.

Here the post...

I have my own NT4/IIS4 websever that I want to host a Application Suite download and support website. I would like to have access to the website by normal IE surfing and thur the application UI maybe using the IE ActiveX componet /or my own custom download content and then display content.

I would like secure user/pass access to some area. I plan to use SQL/MSAccess/ODBC(I will later look for powerful/low costing DBM) for user accont DB but flat comma delimited is fine for now. I would like to use redirects that work in the IE address like the form POST method but I would be using only hyperlink and setting some kind of envierment variable. These redirects are may only be needed for IE access and not thur app access. Also I think the pages will be made only for how they will be accessed thur IE/App. I also want all scripts to be unseen thur IE View/Source I know for PHP and ISAPI it possible to hide the server-side script.

What I know about PHP, ISAPI, and ASP.

I have created only two working page in PHP useing form POST method but not the link redirects I discussed above. I have not use ASP and ISAPI but I have look at codeing ISAPI and it uses VC++/MFC which I been using for two years. I have found many PHP bugs. And if I can stay with Microsoft product it will be better.

Any answser...
