Perl Back Button Issues.

[rdyoll]

I'm trying to come up with a Perl back button in my scripts. I know using the referer will produce this, and generally suits me fine, but sometimes I want to return to the prior invocation of my script and retain the exact state it was in. So, using the self_url() returns the current state of the page...not the prior one. I know I can use javascript (history.back()...etc, but, if it's possible to use perl, I'd like to see.

For you to send the client to the last page they visited, they'd have to tell you where they were. In short, there's no way to guarantee that. Client-side Javascript has a better chance, but that can be disabled in any respectable modern browser. I could be wrong, but I don't think there's a reliable way to perform that bit of interface fluff. Browsers have built-in back buttons if the user wants to retreat from your website into their history.

i never tried this but you could do this (i think)

print "Location: $ENV{'HTTP_REFERER'}\n\n";
