Help with ADA CGI

Help with ADA CGI

[george]

Hi there. I would appreciate it if anyone could email me ASAP and give me some 
advice on how to get my ADA CGI program working.
I have the following problem
1)when I submit my ada generated form I cannot get the results to appear on a 
new page
2)if there is an error in the form, I cannot get the program to wait for the 
user to input the missing data, instead it just continues with the output- of 
course it results in 'Your name is      ' etc etc and not what I want.
If the form is submitted blank, it should put another form out and ask the user 
to input the data again, but I can't get it to do this.

If you wish to see my source code, please email me georgeATdodgybloke.co.uk - 
I'm sure you'll work out you have to replace the AT with @, but it's to stop 
spamming bots.

thanks
George

What do you mean by a _new_ page?

Since HTTP is basically a stateless protocol, a CGI program
can not wait for the user.

Sounds like a logical flaw on your program. Define 'new page' in this
context. Post the code.

Ditto. Sounds like you are not checking for null input. Again, post the
code.

Really sounds like like flaws in CGI, not Ada, programming. But post the
code anyway. And is it homework?

What CGI interface are you using ? GNAT.CGI ?

<Plug mode on>

To build Web Based servers why not use AWS instead of the old CGI way ?

<Plug mode off>
