A Few Questions

Hello,

I am working on a CGI script. It works fine from the command prompt.

I am using Net::SMTP and strict.

When I try to pass this script through a web parameter, it ends in
"Internal Server Error".=20

I tried using ReadParse() routine. All the variables are coming from the
web. In the process of writing the script, I have coded all variables in
the script itself.

Any thoughts would be appreciated. If you would like to look at the
script first, please let me know.

I am a beginner with Perl/CGI programming.

Thanks.

You will need to look in your error log to see what the actual error is.

Probably a permission error. Your web server will run under a
different user so unless your scirpt is executable for the correct
user/group, you will see that error.

Often this is caused by not outputting a proper header. The very
first thing your program should output is a header like:

Content-Type: text/html; charset=ISO-8859-1

If your program emits any output other than this you will get an
internal server error.
Note that the header must be followed by a blank line, if you are not
using the CGI module you need to have:
print "Content-Type: text/html; charset=ISO-8859-1\n\n";
as your first line of output.

There is a function/method in CGI called header that will do this for
you is you are using the CGI module. See perldoc CGI for more info.

If this doesn't work please post your script.
