in thread redirect back to where you were

You can jump back two pages if you dynamically generate the form from a cgi script. What I do is leave the electronic equivalent of bread crumbs.

I put $ENV{'HTTP_REFERER'} into a hidden form field inside my dynamically generated form.

<form>
--------- stuff ----
<input type="hidden" name="backpage" value="$ENV{'HTTP_REFERER'}">
<input type="submit">
</form>

Now you are free to redirect them in the final, form processing, script to CGI::redirect($input{'backpage'}).

(Actually, I'm not so sure what CGI.pm puts it's input into, because I don't use it. But you get my meaning.)

    I knew about JavaScript trick, but I like more trick with using $ENV{'HTTP_REFERER'} and will use it in my current project. Why? It works also if client disabled JavaScript (as I did recently).
    Quite often I'll also just add plain link (or submit button) like {Back to Main Menu} or {Close All Open Issues}, just to bypass multiple {BACK} commands and start fresh. Sometimes it's easier for users to start afresh.

    To make errors is human. But to make million errors per second, you need a computer.
