Hi dude! I have an orrible trouble with this poor cgi: is a client
pop3 web based gateway.The function "connetti()" never been called and
i don't know why!!The functions in the bottom of the script
load,save,restore the state of the session by save the
user,pass,host,id in a file.if you try to execute the script all stop
when you click on the submit button.I'm italian so i apologize for the
bad english.
I hope there is a good soul who help me.
There is the code:
#!/usr/bin/perl -w
