How do you rewrite urls?

[graphixela]

I'm used to doing this with htaccess but I'm on an nginx server.
I tried multiple things and nothing worked. I'm guessing because WinterCMS has it's own rewrite logic.
I'm stumped as to what I'm supposed to do.

I have /agent?name=variable and I'm trying to get the variable to be the subdomain and stay on the same page.
So /agent?name=graphixela becomes graphixela.domain.com

location ~ ^/agent?name=([^/]+)(.*)$ {
    rewrite $1.example.com$2;
}

The last few I had were
rewrite agent?name=$1 ^agent/([0-9]+)/?$ break;
rewrite ^/agent$ /agent/?name=$1 last;
and I know those don't do the subdomain but I was trying to get something simpler to work. I also tried with index.php before the Winter rewrite was called. I'm confused as to which URL variable is supposed to go first as I've seen both in examples that are supposed to do the same thing.
I don't know if I need to use try_files before either.
Apache was so much easier. Any help would be appreciated.

Please post your nginx config. This is more of an nginx question than a Winter CMS question, although you could perhaps try using the Winter.Redirect if you would like.

I tried redirect and it worked but it brought the subdomain back to the homepage which isn't correct,

Here is the config

server {
    listen      %ip%:%web_port%;
    server_name %domain_idn% %alias_idn%;
    root        %docroot%;
    index       index.php index.html index.htm;
    access_log  /var/log/nginx/domains/%domain%.log combined;
    access_log  /var/log/nginx/domains/%domain%.bytes bytes;
    error_log   /var/log/nginx/domains/%domain%.error.log error;

    include %home%/%user%/conf/web/%domain%/nginx.forcessl.conf*;

    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

    location = /locationlist.json {
        allow all;
        log_not_found off;
        access_log off;
    }

    location = /markers.xml {
        allow all;
        log_not_found off;
        access_log off;
    }

    location / {
        rewrite ^/agent$ /agent/index.php?name=$1 last;
        rewrite ^/.*$ /index.php last;
        try_files $uri $uri/ /index.php?$args;
        location ~* ^.+\.(ogg|ogv|svg|svgz|swf|eot|otf|woff|woff2|mov|mp3|mp4|w>
            expires 30d;
            fastcgi_hide_header "Set-Cookie";
        }

         location ~ [^/]\.php(/|$) {
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            try_files $uri =404;
            fastcgi_pass %backend_lsnr%;
            fastcgi_index index.php;

@graphixela My understanding of your question is that you want the following redirects to occur:

• domain.com/agent?name=foo to redirect to foo.domain.com
• domain.com/agent?name=bar to redirect to bar.domain.com

And that any part of the URL after ?name= is tacked on to the end of the redirected URL - ie.

• domain.com/agent?name=foo/next/page to redirect to foo.domain.com/next/page

I'm not quite sure that's possible. You are using a query string for the name variable, which by conventions of RFC 3986 can only be followed by a hashbang. You can't follow it up with more path sections.

You can most certainly do these rewrites though:

• domain.com/agent/foo/next/page to redirect to foo.domain.com/next/page
• domain.com/agent?name=foo&path=next/page to redirect to foo.domain.com/next/page

[graphixela]

You're combining the two. The second example I used was just to demonstrate it wasn't working.
I just need the first part:

domain.com/agent?name=foo to rewrite to foo.domain.com

But it needs to stay on the agent page. Basically it's a mask/rewrite instead of a redirect.

I know I can do something. My issue is nothing is working and I don't know why that is.
As you can see in my config file I had tried to save markers.xml to the root directory and it didn't work even thought it should. I ended up just saving it to assets.

Changing the URL did work with the redirect plugin but it goes to the homepage instead of staying on the current agent page.
Seeing as how the plugin does redirects and not rewrites, I don't think the plugin would work for my case. Unless I'm missing something.

[bennothommo]

Right, so what you're saying is that domain.com/agent?name=foo redirects to foo.domain.com, and you would like foo.domain.com to actually mean (according to the PHP side) the original domain.com/agent?name=foo.

It's gonna be difficult, but it is possible.

You're going to need to be able to extract the subdomain portion first from the server_name, which means that you'll probably want this in its own server block, and will likely need to copy the entire config you have there now so that Winter and assets still work correctly.

server_name  ~^(?<subdomain>.+)\.domain\.com$;

The above extracts the subdomain portion to a variable $subdomain. Then you'd need to dynamically set the REQUEST_URI parameter in FastCGI. Something like:

fastcgi_param  REQUEST_URI /agent?name=$subdomain

This needs to occur after the following line:

include /etc/nginx/fastcgi_params;

Since by default, Nginx will simply set REQUEST_URI to be the request URI sent in the browser.

Given all the placeholders in your config, I'm assuming you're using a webhosting platform, so you may need to be careful with this, as I would assume that platform will likely rewrite or modify the config and may override your changes. Hopefully however, this should give you enough to go on.

Good luck!

Thanks Ben. I appreciate it.

I have my own VPS so I'll just make another template.
