重定向|从旧网址转发到新网址

Question

I had a route and a method that manipulated URLs in this way:

http://domain.com/combivent?email=WGA1cUtKZi4

Now that URL has changed into this one:

http://domain.com/?email=WGA1cUtKZi4

But old emails still keep the old one. I need to redirect each URL from the old way to the new one. For example if I call this http://domain.com/combivent?email=WGA1cUtKZi4 then I should redirect to http://domain.com/?email=WGA1cUtKZi4 how I can achieve this in Symfony2? Can I use any kind of wildcard in routes or do I need to keep both methods and handle this internally? Can this be done at .htaccess level? Any advice?

This is how the .htaccess looks like:

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]

    # Remove combivent word from the URL when call a brand page
    RewriteRule ^combivent?email=([^/]+)$  /?email=$1 [L,QSA,R=301]

    RewriteRule .? %{ENV:BASE}/app.php [L]    
</IfModule>

Furthermore this domain.com is a Alias of a VirtualHost that share three domains. Think in the VH definition as:

ServerName maindomain.com
ServerAlias domain.com
ServerAlias domain1.com

Update

Below is the full .htaccess definition:

DirectoryIndex app.php
<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    # Remove combivent word from the URL when call a brand page
    RewriteCond %{QUERY_STRING} ^email=[^&]+ [NC]
    RewriteRule ^combivent/?$ / [L,R=301]

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]

    RewriteRule .? %{ENV:BASE}/app.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 302 ^/$ /app.php/
    </IfModule>
</IfModule>

Answer 1

Rather than digging into the .htaccess you could just redirect the old route to the new route in your routing.

new_route:
    path: /
    defaults: ...

old_route:
    path: /combivent
    defaults:
        _controller: FrameworkBundle:Redirect:redirect
        route: new_route
        permanent: true

As you are using annotations you would just need to either name your new route or find out the generated name and use that in your "old_route" definition.

Updated with your actual setup

PDOneBundle/Resources/config/routing.yml

pdone:
    resource: "@PDOneBundle/Controller/"
    type:     annotation
    prefix:   /

# add this
combivent:
    path: /combivent
    defaults:
        _controller: FrameworkBundle:Redirect:redirect
        route: brand
        permanent: true

PDOneBundle\\Controller\\BrandPageController

class BrandPageController extends Controller
{
    /**
     * @param Request $request
     *
     * @return array
     * @Route("/combivent", name="combivent") <!-- remove this
     * @Route("/", name="brand")
     * @Method("GET")
     * @Template()
     */
    public function indexAction(Request $request)
    {
        ...
    }
}

Answer 2

Just add the following rule to your .htaccess file:

RewriteEngine On
RewriteRule ^combivent?email=([^/]+)$  /?email=$1 [L,QSA,R=301]

Edit: You need to add it above the following line:

# Rewrite all other queries to the front controller.
RewriteRule .? %{ENV:BASE}/app.php [L]

Answer 3

This rule is problematic:

# Remove combivent word from the URL when call a brand page
RewriteRule ^combivent?email=([^/]+)$  /?email=$1 [L,QSA,R=301]

as you cannot match QUERY_STRING using RewriteRule . Use a RewriteCond instead:

# Remove combivent word from the URL when call a brand page
RewriteCond %{QUERY_STRING} ^email=[^&]+ [NC]
RewriteRule (?:^|/)combivent/?$ / [L,R=301]

QUERY_STRING will be carrier over to nee target automatically.

Full .htaccess:

RewriteEngine On

RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]

RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

# Remove combivent word from the URL when call a brand page
RewriteCond %{QUERY_STRING} ^email=[^&]+ [NC]
RewriteRule (?:^|/)combivent/?$ / [L,R=302,NC]

RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .? - [L]

RewriteRule .? %{ENV:BASE}/app.php [L]

Also make sure to clear your browser cache before testing this.
