Hi All,
I have prototyped a large web application using Ruby and InterBase but the performance seems to be not good enough to code it in Ruby or any other scripting language. Seen I am an old Pascal fan and I after have tried and programmed in many other languages I still consider Pascal the only true high level general purpose language. Now I wonder if I can use it even for a large web application seen the problem of performance will surely go with FPC.

My application would contain a main application running in memory and permanently connected to InterBase with many little others applications running as CGI who access to the main one in momery. So, could somebody point me how to write daemon applications in FPC? Or just how to comunicate with a FP running application?

Every hint is welcome :-)

Sorry about the delay in answering, I had some trouble with my mailserver.

As far as daemonizing is concerned I reccomend checking the examples/demos folder of the FPC documentation, there is a fully working example of a daemon
there.

I would also recommend you do not use many small programs, it is hell to debug
and worse to maintain. Rather I have found (and I have written severall large
web apps in FPC) that the best approach is something like this.

procedure page1;
---snip-----
procedure page2;
----snip-------

Begin {Main}
--insert standard CGI headers here, as well as common html headers for all --pages - that way you can change the look and feel without modifying anything
---else

If paramcount=0 then
begin
---The main (first) page of your app goes here-------
end;
If paramstr(1) = 'page1' then page1;
if paramstr(1) = 'page2' then page2;
end.

Now to get to page2 for example your link (or form action) would be myapp.cgi?page2
