Recently, I had noticed lots of 404 error generated by my wordpress software. My old wordpress tag structure changed from:
/tips/tag/linux_software
/tips/tag/one_two_foo
To:
/tips/tag/linux-software
/tips/tag/one-two-foo
As a result lots of error 404 was dumped into my log file. I wrote a small php code to get rid of the problem:
My tag301.php:
<?php $newTagUrl='http://www.cyberciti.biz/tips/tag/'.str_replace('_', '-', $_GET['r']); @include_once("../include.genlib.php"); movePage(301, $newTagUrl); ?>
Finally, I updated my mod_rewrite (lighttpd rewrite engine) to redirect to new location:
"^/tips/tag/(.*_.*)+$" => "/tag301.php?r=$1"
Code for movePage() is here.

Nice info… bookmarked – just incase I think of changing URL structure 🙂
A WordPress plugin that replies a 301 permanent redirect, if requested URI is different from entry’s (or archive’s) permalink. It is used to ensure that there is only one URL associated with each blog entry.
