Thanks for the suggestion. Unfortunately, I probably didn't explain this
well enough in the rush to send it.
Apache buffers all the output of the cgi until the cgi is done. After the
cgi is done, then the user sees whatever was generated. If the cgi crashes
during execution, no output (including error messages I might have put in)
will be shown.
One of the first things done in the cgi is to write the appropriate <html>
tags, so I can see any errors that might occur. The, around suspect bits of
code, I'll put a statement like:
printf("the SQL query is: %s", query);
exit(0);
This will print out the query, then exit right after. The exit() tells
apache "The cgi worked fine, you can send it as html output now."
Notice that I don't put terminating </body></html> tags after the message,
as they are not necessary for the browser to display the output.
Regards,
Alex
