For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Retired web pages

Posted by admin (Graham Ellis), 29 August 2004
How do you replace a URL on your website and keep your search engine placement intact, and maintain continuity for anyone who's bookmarked the page and / or arrived via a search?

When we replace a page, we don't simply scrap the old one - we also provide an onward reference in the old location for a year or so.   Here's the script that generates the onward reference:

Code:
sub makereplaced {
       @gone = @_;
       print "making replaced pages\n";
       open (FHI,"alternative");

       while (($_=pop(@gone)) or ($_=<FHI>)) {
               ($was,$becomes) = split;
               $becomes ||= "resources/replaced.html";
               open (OUT,">$t2/$was");

# refresh = needs to be added to following ...

$html = <<"SIMPLE";
<head>
<meta http-equiv="Refresh" content="7; URL=/$becomes">
<title>Replaced Page</title></head>
<body bgcolor=white>
<H2>Replaced Page</H2>
This page has been retired. Your browser should call up the replacement
in a few seconds, but if it doesn't please select one of the links below
yourself. Thank you.<BR><BR>
Please follow <a href="/$becomes">this link</a> for the alternative page.<P>
Please follow <a href="/index.html">this link</a> for our home page.<P>

               print OUT $html;

               }

       }


Note:

1) that we can specify replacements in a file and / or as a list of parameters to this script.

2) the replaced page automatically refreshes forward to the new page via a meta tag, but there's a link too from crawlers and other browsers to follow

3) This page inlcudes NO CLUE AT ALL as to what was on the replaced page.  This is intentional as we don't want it re-indexed and re-bookmarked - we want that for the NEW page!
