.htaccess将所有子目录重定向到新位置

Question

I have users coming to my website from different sources (forums, blogs...) with links that does not exist no more, so a 404 error shows up. Base on the link they access on my website, I know where to send them. So the links are like this:

www.test.com/shop/customers/individuals/343a/?shopc=variable
www.test.com/shop/customers/company/445a/?shopc=variable
www.test.com/shop/b2b/discount/43b/?shopc=variable
...

and so on

As you can see all the links have www.test.com/shop/ and the variable shopc . What I want to do is to redirect to the correct location. Let me give you an example of 2 user accesing my website and what I want to do. So the users are entering my website with this urls:

www.test.com/shop/low/index.php?shopc=variable
www.test.com/shop/company/b2b/index.php?shopc=variable

Right now a 404 error is displayed because that files and dir

/hsphere/local/home/danuser/test.com/shop/low/index.php
/hsphere/local/home/danuser/test.com/shop/company/b2b/index.php

does not exist on my website no more. But base on the shopc variable I know where to redirect them.

So the question is: Can I create a .htaccess file to redirect links like

www.test.com/shop/company/b2b/user/index.php?shopc=variable

to

www.test.com/shop/index.php?shopc=variable

so I can grab the shopc variable and redirect them to the proper location?

Answer 1

In the shop directory's .htaccess file:

RewriteEngine On
RewriteBase /shop

RewriteRule ^.*$ index.php [L,QSA]

The flag QSA automatically appends the query string on to the substitute request. That's how 'shopc' is passed along. See Apache mod_write online documentation for more.

When I go to this URL:

http://localhost/shop/company/b2b/user/index.php?shopc=variable

...I get this output from print_r($_GET) in my /shop/index.php file:

Array
(
    [shopc] => variable
)
