Hi guys, I am working on a CGI script for Email Management. When I call one cgi(main) from the other(sub.cgi) (on say form submit). I want to return to the main.cgi again, and get the value by appending the value pair to the url. This is working fine, however, everytime I pass a value to sub.cgi, it gets appended at the URL string. This makes the URL really long if the user navigated back and forth a lot. To eliminate this, I have written below code. $orig_url = $ENV{'HTTP_REFERER'}; #if ($orig_url = !~/$email_box/) { if ($orig_url !~ /&email=/) { $orig_url .= "&email=$emailadd"; } To make sure, if there is already no value pair added, then only I add it. I suppose as the URL initially doesn't contain the string email_box, it will get the value '', hence the if check is failing always. Also, can someone suggest a way to trim off the previous value pair for email_box=$emailadd, and always append only the latest.(I think this is a better way of doing it) Appreciate suggestions and help. -Subbu _______________________________________________ Perl-Unix-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs _______________________________________________ Perl-Unix-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
