Thank you all for your reply.

But, the problem of logging is different now in my implementation.

I have a server-client code based on Apache.

I tried to create a custom log using the log module of Perl, but I didn't have permission to write to the file.

While exploring, I did get Apache2::log module, which writes the error into error.log file of httpd properly.

The problem now, is how can I have my own log file.

Please help.
