Eion,
I would concur with Nic - dump the section of the book - forget CGI and use
any one of the 3rd party tools. There are a couple that is not on Nic's
list:
Cold Fusion - written in Delphi, script like, now can call Delphi code.
Probably THE favourite Delphi web tool.
ASP Express - (its free, you pay if you want the source) written in Delphi,
extension to ASP and lets you design forms using the IDE (Nice). Haven't
used it in a production environment.
My opinion on the other Delphi technologies:
ASP - full of VB scripts that call COM objects, which you would write in
Delphi. Good for simple low volume sites - need a lot of RAM if you have a
lot of users. Has a number of known security holes, especially if you try
to connect to ADO directly from vbscript. Possible to crash IIS from the
COM objects.
WebHub - still my preference. Written in Delphi (100%), script like and
calls Delphi code. Supports many technologies, including ISAPI and CGI.
Good separation of HTML from code. Your web application runs in a separate
process space from IIS, so its not possible to crash it. Steep learning
curve & vendor not very stable right now. Free deployment license for
smaller sites.
ISAPI DLL - steer clear of this if possible. Your application runs in the
same process space as IIS. It is a nightmare to debug, and if you get
anything wrong, you stand a good chance of crashing IIS! Need to write
multi-user, multi-threaded code.
CGI - Very slow and resource intensive - every page request results in your
app being started and stopped. Can result in huge number of instances of
your application running at any one time.
Basically, with the last 2 options, you have to do everything yourself - its
like writing a windows app using purely WinAPI.
Regards,
Dennis.
ps. Tell your VB contractors to start using a *REAL* language.
