Tested up to: 3.1
Stable tag: 3.2
Mask all external links - make them internal or hide. On your own posts, comments pages, authors page - no more PR\CY dropping!

== Description ==
>**Check out new feature - masking links to digital short code!**
>Versions 3+ have many cool features - outgoing clicks stats, fulllink masking, custom redirects and so on - but it may be not compatible with strange server configurations. Any feedback is much appreciated. If plugin is not working for you - [try 2.172](http://downloads.wordpress.org/plugin/wp-noexternallinks.2.172.zip).

>If you upgraded to version 2.10 and higher and have problems - please [download version 2.05](http://downloads.wordpress.org/plugin/wp-noexternallinks.2.05.zip) or help me to debug - currently It seems like I'm having problems with blogs on PHP4.

>If you are having problems even with 2.05
>Then please [download version 0.071](http://downloads.wordpress.org/plugin/wp-noexternallinks.0.071.zip) - it's slower, doesn't have functionality, but works fine on servers with the worst settings. 

>Still not good?
>Tell me about your problems in [my blog](http://jehy.ru/articles/2008/10/05/wordpress-plugin-no-external-links/).

This plugin is designed for specialists who sell different kind of advertisment on their web site (for example, with [sape](http://www.sape.ru/r.f6054dfcc2.php) system) and care about the number of outgoing links that can be found by search engines. Now you can make all external links - internal! In your own posts, comments pages, authors page... Plugin does not change anything or write to base - just processes output.

Now you don't need to worry about your page rank or index, dropping because of spam bots. You write any kind of http link - and it becomes internal or hidden! Of cause, all the links will still be usable :).

####Version 3.2 implemented:   
+ Completely removing links from your posts (someone requested this option)   
+ Masking links to text. Option for perverts.   

####Version 3.1 implemented:  
+ Masking links with digital short codes    

####Version 3.0 implemented:    
+ Outgoing clicks stats    
+ Javascript redirect with custom text and timeout    
+ .po file translation (sorry, now only english and russian versions are available)    
+ FULL link masking    
+ No masking for registered users    

####Version 2.0 implemented:
+ You can configure plugin to mask ALL LINKS on your blog - including widget, theme footer, etc.    
+ Now you can also disable link rewriting, and use **"rel=nofollow"** and **<noindex>** tag instead of it - everything as you wish!   
+ From version 2.0 you can **make all links open in new window!**   
+ After many requests, I finally made an option to **disable masking** for concrete URLs and posts.  
+ Plugin works now without any magic with .htacess - you just install it and it works, and determines itself, if you need to rewrite permalinks, or use default link structure.  
Have fun!

####Example

In short, your links like "http://gmail.com" will be masked into  
"http://YourBlog.com/goto/http://gmail.com" - or  
"http://YourBlog.com?goto=http://gmail.com"

Now you can even tansform simple link "<a href="http://google.com">google</a>" to   
"<noindex><a rel="nofollow" target="_blank" href="http://google.com">google</a></noindex>"

####Just one poplular question :)
>  **- Is it an evil hack and black SEO?!**   
 - Before you say such awful things, read at least [Google's topics on SEO](http://www.google.com/support/webmasters/bin/topic.py?topic=8522)   

####Note
<noindex> tag is used mostly by russian search system "Yandex" (yandex.ru), and non-russian users don't usually need it.

== Frequently Asked Questions ==
####How can I exclude my page with links from masking?   
Now you just put URLS you need to the exclusion list, or disable masking for concrete post - and everything's OK!!!

####How can I mask links in custom field?
You will have to add just a line in theme code where you output custom field data.    
To add same preprocessing for data as for comment text, use    
    $metadata=apply\_filters('comment\_text',$metadata);    
For example, if you use some kind of metadata, it should look like this:    
    $metadata = get\_post\_meta($id, 'MetaTagName', true);// get data from wordpress database    
    $metadata=apply\_filters('comment\_text',$metadata);// add this line of code for preprocessing field value    
    echo $metadata;//output preprocessed field value    

That's if you want to mask links in custom field like in comments text. Use "the\_content" instead of "comment\_text" if  you want to use the same masking policy as for post text.
