rename request hostname

[Yoel Benitez Fonseca]

h!

Is it possible to change the hostname that comes in the form request  so that outbound links have the hostname i want?

I have an app in an internal network that I want to make visible from the outside with an nginx proxy, all relative links work correctly, this would be the example of configuration in nginx:

location ~* ^/(\w+)/static(?:/_[\d]+\.[\d]+\.[\d]+)?/(.*)$ {

         rewrite ^/(\w+)/static(?:/_[\d]+\.[\d]+\.[\d]+)?/(.*)$ /some-folder/statics/staging/$2 break;

    proxy_ignore_headers Cache-Control;

    add_header Cache-Control public;

    add_header Cache-Control max-age=31536000; # seconds, one year

    proxy_pass_request_headers  on;

    proxy_pass https://some.internal.server.local;

}

location ~* ^/(.*)$ {

    rewrite ^/(.*)$ /staging/$1 break;

    proxy_set_header Host "some.internal.server.local";

    proxy_set_header X-Real-IP $remote_addr;

    proxy_ssl_server_name on;

    proxy_pass https://some.internal.server.local;

}

That works correctly for any relative link, the problem comes with uploads, whose links are being generated for some reason including the hostname:

https://some.internal.server.local/app/download/some.object.a051462ffdcb77a3.746d706c32417038422e6a7067.jpg

and how it happens, i can't change the internal server name and need to pass the proxy_set_header Host or I will not have access to that host... The only thing I can think of is telling WEB2PY to use a fixed host name when generating the links.

I think you want to look at routes.py, but I haven't tried this use case, so any details I could give you are in the book.

No, I know what my mistake is, some of the links are generated by URL, using the host and scheme parameters. In case it serves anyone else, all this is deploying the app as a lambda funsion on AWS with zappa with an NGINX in front as a proxy.

I guess I will have to hard code  the host directly in the code.

I believe the pattern-base system for routes.py can handle this.  The examples in the book  include mapping IP in the range 140.191.x.y to www.web2py.com
