Hi Mark,
Laisvunas is my real name. Sound strange those all names from new member-states for English ears aren’t they? 
Just out of interest though (and I probably missed this in the thread somewhere) why does it work with {if} conditionals when you use a javascript location redirect but it won’t work with a PHP one?
I do not have exact answer on this but it seems that PHP redirect can only occur before http headers were sent; in contrast javascript redirect can occur anytime.
When posting modified version of the Redirect To plugin I forgot to include udated usage() function. Here is it; it’s text may also be useful when writing instructions.
function usage()
{
ob_start();
?>
This plugin is exceptionally simple to use. Place the following tag on any template as shown below :
Using full URL - useful for external sites.
{exp:redirect_to location="http://www.yahoo.com"}
or using paths instead - useful for internal links.
{exp:redirect_to location="news/detail/news_story"}
By default PHP redirection will be performed. If PHP redirection does not work,
use javascript redirection by adding method="script" parameter.
{exp:redirect_to location="news/detail/news_story" method="script"}
If it is impossible by usual means to check if condition for redirection was met or not you can
check it by wrapping the code expressing condition by {exp:redirect_to}{/exp:redirect_to} tags.
Redirection will be performed if the code wrapped by {exp:redirect_to}{/exp:redirect_to} tags will produce
no output.
{exp:redirect_to location="my_template_group/my_template" method="script"}
{exp:query sql="SELECT title FROM exp_weblog_titles WHERE weblog_id = '5' AND url_title ='My title'"}
{title}
{/exp:query}
{/exp:redirect_to}
If you want that redirection would be performed on condition that certain output were produced, you should
enter expected string as a value of "tagdata" parameter. Then the redirection will be performed if
the string entered as "tagdata" parameter value and output of the code
wrapped by {exp:redirect_to}{/exp:redirect_to} tags are identical. (Tabs, spaces and new line characters
will be stripped.) In example below redirect will occur if {exp:query tag} will produce string "1".
{exp:redirect_to location="my_template_group/my_template" tagdata="1" method="script"}
{exp:query sql="SELECT title FROM exp_weblog_titles WHERE weblog_id = '5' AND url_title ='My title'"}
{total_results}
{/exp:query}
{/exp:redirect_to}
<?php
$buffer = ob_get_contents();
ob_end_clean();
return $buffer;
}
