The Joomla! Extensions Directory ™

The component does exactly what it says. If you had to change a category name or menu, this is ideal to keep seo positioning.
is so simple that I can upload all the new url from phpmyadmin without any problem
Excellent!

Tried REDJ first but had problems getting it working. Switched to Phoca SEF which supplies very similar functionality and got it working in several minutes as you can read below!

A bit of PHP copy and pasting into a file is a bit of trouble to go through but it is not that bad at all. It would be better to give a code sample so others can understand how libraries/joomla/error/error.php should look like after you inserted the required code:
function & raiseError($code, $msg, $info = null)
{
//PHOCAEDIT
if ($code == '404') {
include_once( JPATH_ADMINISTRATOR.DS.'components'.DS.'com_phocasef'.DS.'helpers'.DS.'phocasef.php' );
PhocaSefHelper::createUrlEntry();
}
$reference = & JError::raise(E_ERROR, $code, $msg, $info, true);
return $reference;
}

Search friendly urls where already enabled.

Hit a couple of those bad Google crawl errors to check if it works. Bang! Found it. I added a simple rule to a landing page, tested it again, it was fixed. Also fixed immediately my favicon.ico because the directory was modified with htaccess. The site improved much already in just several minutes of work.

A feature I would really like to see added that hurts all of us when you switch to a new plugin for your calender or pictures:
Right now every single url (all those long ones are the bad guys) of a page that has been moved must be done separately. If we can add the source like /pictures?.... rather into /pictures* then it would fix all references to the incorrect page at once. Single action all issues resolved, that would be a very nice addition. Meanwhile I remain very happy with the current functionality.

First the bad:
1) poor English translation.
2) Core hack required.

Okay, now the good:
1) I didn't have to write this stuff myself!!

This plugin does exactly as described:
1) It logs all requested urls that are not valid (404 errors).
2) Allows you to map old/missing URLs to new URLs (one to one mapping, no wild cards).

I restructured my site to use K2 for all content thus changing all URLs of my content. Internally, this is no big deal since I could just fix any bad links. However, what about all the external pages that link to my site? All those links would be broken if it were not for Phoca SEF! It's not 100% automatic, but it's light years easier than the alternatives I thought of.

It's excellent, only why is it a hack? Maybe you could alternatively supply a plugin - core hacks aren't always possible.

Very easy installation and usage. It is also possible to add urls manually.

Note: You have to edit Joomla core file to get this work.

Revamped my site and ended up with a number of 404 – search for a solution found this – installed it – worked like a charm.
Thanks

This very simple and plug-and-play component is very useful when moving to Joomla existing sites, and you want to preserve existing links, for example indexing in Google Search...

After installing (it needs a Joomla core file editing, not very good but it's simple) it monitors all 404 errors received on the site, and for them you can set the auto-redirect url. So users don't see anything and you don't lose visit!

It works with Joomla 1.5 native SEF urls, that is very good for me.

Thank you to Phoca!!!

Nother GREAT component, just love it.
Only had to do the file for a second time before I dropped code in right place, but after that it worked, 100%! Good component, it works and yes it works!

If you only need a simple redirection utility then this is it! Installation is pretty straight forward and it is easier to edit error.php than .htaccess - just. :-)
Also need to remember that if redirecting old site links you only need the part of the link after the domain name. I guess this should be obvious but it caught me for about 30sec!!
Great work Phoca.

Very simple to implement - I was migrating a client's site written purely in html into Joomla. They had good page results in google and I didn't want these lost. Using Phoca SEF allowed me to redirect the old html addresses to the new page locations so users won't be stuck with the old 404. Thanks for this component!

Nice component when you have changed your website a couple of times and didn't know or thought about redirection. I had lots (1000+) of 'not founds' in the webmaster tools of Google and reduced that number increasingly in couple of weeks.

It's also handy if you are going to change the website a little (like depublish one article and have one other article instead)

Also nice to see the referring sites. So you know if you have to update some really old article or something like that.

And of course is the support superb (as with all other Phoca extensions)

Brilliant little component that does exactly what is says! Automatically collects 404 errors. All you need to do is add a new link and the page request will be redirected.

Very useful component if you are using core SEF.

Thank you.

Recently change the structure of my site. This component is the answer if you want to keep up with the changes, especially if you got outdated links within your articles. This extension will track everything you need to know and also will enable you to redirect old links to the new ones (great for SEO).

Thanks for this valuable tool.
