301 – Moved Permanently
302 – Found – the original describing phrase was “Moved Temporarily”
307 – Temporary Redirect (since HTTP/1.1)

If you notice, usually we use 302 as temporary redirect. Now.. change it to 307.

Bagaimana untuk selamatkan trafik dari url lama daripada paparan page tidak dijumpai atau 404 error. Contohnya, url lama bagi salah satu pos saya adalah http://ibnuyahya.com/simple-jakim-esolat-wrapper/lang/en-us/. Memandangkan saya tidak lagi menggunakan plugin multi-language.. maka url tersebut tiada post-fix /lang/en-us/. Jika pelawat menggunakan enjin carian google atau yahoo dan menjumpai link tersebut dan klik… maka mereka akan di bawa ke laman error 404, iaitu page berkenaan tidak dijumpai walaupun sebenarnya page tersebut berada di http://ibnuyahya.com/simple-jakim-esolat-wrapper , tanpa post-fix /lang/en-us/

Jika anda menggunakan apache, sila masuk http://ibnuyahya.com/htaccess-redirect-old-post/

Untuk server nginx, anda boleh gunakan rewrite kod seperti berikut

rewrite ^/(.*)/lang/en-us/$ /$1 permanent;
rewrite ^/(.*)/lang/ms-my/$ /$1 permanent;

Dengan menambah kod di atas di dalam nginx config , anda boleh redirect url lama dari http://ibnuyahya.com/simple-jakim-esolat-wrapper/lang/en-us/ ke http://ibnuyahya.com/simple-jakim-esolat-wrapper/ dan setkannya sebagai move permanent atau 301.

I had a small problem after I remove xlanguage plugin from this website. All the links coming from search engine was return 404 error “page not found” .This is because of the different url format which is http://ibnuyahya.com/my-article/en-us/ for the old format while http://ibnuyahya.com/my-article for the new format.

This htaccess was solved my problem ;p

RewriteRule ^(.*)/lang/en-us/$ http://ibnuyahya.com/$1 [L,R=301]
RewriteRule ^(.*)/lang/ms-my/$ http://ibnuyahya.com/$1 [L,R=301]

[lang_en-us]In codeigniter, standard fromat for a URL is like this

http://ibnuyahya.com/class/function/id/

maybe this URL is too long and you want to make it shorten like

http://ibnuyahya.com/go/mylink and will route to http://ibnuyahya.com/link/redirect/mylink/

How to do that?
We can create our own route in system/application/config/route.php and add new route rule for example

$route['go/(:any)'] = "link/redirect/$1";

[/lang_en-us]
[lang_ms-my]biasanya codeigniter URI Route akan menggunakan format berikut

http://ibnuyahya.com/class/function/id/

mungkin url ini terlalu panjang atau kita mahu membuat routing roles sendiri seperti

http://ibnuyahya.com/go/mylink akan pergi ke http://ibnuyahya.com/link/redirect/mylink/

Bagaimana untuk melakukannya?
kita boleh membina route rule kita sendiri di dalam fail system/application/config/route.php seperti

$route['go/(:any)'] = "link/redirect/$1";

[/lang_ms-my]
