Wordpress How to have conditional redirect for nginx?

Hi,

I have a situation like this:

I have a redirect in nginx:

Code:

location /old-url.html {
   rewrite ^/.* http://$server_name/new-url.html permanent;
}

My purpose is for people from outside of my site, go to old-url, they will then be redirected to new-url. But when they are in my website and after doing some tests, they click the link to the old-url

So, within the new-url page, I have a "click here" link which linked to old-url, therefore they can go to the exact old-url.html not new-url.html anymore.

But with the redirect in nginx above, I make the visitor go to only new-url.html, like a loop.

Can this be possible to do with nginx? If, yes, how can I do? I am using Wordpress (with Centminmod + Cache Enabler) but I don't want to touch too much in the code or plugins of my wordpress site.

Thanks a lot!

After a while of searching, I am trying this:

Code:

location /old-article.html {
    if ($http_referer !~ (www\.)?mydomain\.com) {
    return 301 http://$server_name/new-article.html;
    }
}

When accessing the old-article while browsing mydomain.com, it returned 404. Dont' know what I did wrong.

 

Just an update, I found a solution, with this config:

Code:

location /old.html {
        root /home/nginx/domains/mydomain.com/public;
        try_files $uri $uri/ /index.php?$args;
        if ($http_referer !~ (www\.)?mydomain\.com){
        return 301 https://mydomain.com/new.html;
        }
}

 

I am still find way to work around the 301 redirect browser cache, I need to force no cache for redirection ... my solution only works for the first visit, from the second visit, the loop happens.

 

Because the old post has good backlinks, so I don't want to use 302 to get rid of those good links. That's why I use 301. Is there anyway to tell the browser to not cache on the new post url?

 

Thanks for your info. From Google point of view, 302 & 301 don't affect your ranks. On the other hand, People still said that they can maintain/get back their ranks better with 301.

Also, I also look at a bigger scene, like Bing or Yahoo, I read somewhere that they treat 2 of them differently. That's why for my safe bet, I chose the 301
