[HOW?]External(outgoing) URLs redirection using .htaccess

[xendex]

Hi,

I have a question: How can I redirect external(outgoing) URLs from my site using .htaccess, so searchengines will consider them as local.

Here's an example:

http://mysite.com/redir?http://externalurl.com

I have a script(plugin) that can convert common urls(like http://externalurl.com) to the ones above on html-output.

 

P.S. I know about the similar solution using a php-file, but I just want to know how to do the same using .htaccess

 

Thanks in advance.

RewriteEngine On

RewriteRule ^redir?(.*) $1 [L]

 

Should do it.

Thanks for reply. But unfortunately it's not working for me as it have to - for when I click on the url it's just redirecting me back to the frontpage(I tested it on gnix host).

P.S. I'm using Joomla, so there also will be the following code in .htaccess:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php

By the way, I tested the proposed solution with and without it, but the result was still the same.

Hrmmm....  It's redirecting you to the front page?  What do you mean?

 

 

Edit:  Hrmmm....  Just tried it my self, and I see what you mean.

 

 

Messing with it now.

Well, realized earlier that ? was making the r in redir optional.

 

 

RewriteEngine On

RewriteRule ^redir/(.*) http://$1/ [L,R=301]

 

 

Works without http://....  Trying to figure out something not to allow or not allow http://.

Thanks, it really works fine without http:// and with http:// the final link form transforms into something like http://http/externalurl.com/...

Though it's not so big deal, 'cause there'll no problem to remove http:// on output(using php) or is it possible to remove it using .htaccess?

 

P.S. Besides. is there any way to insert = symbol between redir and exterlal URL(like: http://mysite.com/redir=http://externalurl.com) or something like that, so outgoing link will be marked out from site link.

[corbin]

Well the http:// on the rule is required or Apache thinks it's a local URL.

 

 

The http:// could be made optional in the matching though....

 

Something like:

 

RewriteRule ^redir?url=(http://)?(.*) http://$1/ [L,R=301]

 

 

That would make it in the format redir?url=http://google.com or redir?url=google.com.

 

 

Untested so it might not work ;p.

Just redirecting back to the frontpage...

[corbin]

Hrmmm........

 

 

I must be making this harder than it is or something because this shouldn't be hard at all x.x.

[xendex]

So is there any way at least to put  =  between redir and external url?

[corbin]

RewriteRule ^redir=(.*) http://$1/ [L,R=301]

 

 

To be honest, I forgot about this thread.  I need to look at a regular expression reference and remember how to make a group optional.

 

 

I thought

 

RewriteRule ^redir/(?:http://)?(.*) http://$1/ [L,R=301]

 

Would work, but it doesn't x.x.

[xendex]

RewriteRule ^redir=(.*) http://$1/ [L,R=301]

Hm, this one really works perfectly if not using http://
