Is it possible to change the proxied file using NGINX itself?

Question

Nginx

Hello! We have nginx configured as a proxy. The simplest proxy, without redirects and everything else.

location ~* \.(?:m3u8)(.*)$ {
        proxy_pass http://$arg_proxy;
}
location ~* \.(?:ts)(.*)$ {
        proxy_pass http://$arg_proxy;
}

That is, when the playlist server1/playlist.m3u8?proxy=server2 is requested, everything works as it should. The playlist is being proxied. But the playlist also contains links to ts files (for example, "/hls/firs.ts") and these files are not opened through a proxy, since the proxy variable is not passed in the link to the file. It is necessary to give an already changed playlist with links like "/hls/first.ts?proxy=server2" So, is it possible to edit this playlist "on the fly" using nginx itself and add the "proxy" variable to it?

Answer 1

maybe it's nginx.org/en/docs/http/ngx_http_sub_module.html

Answer 2

I will add. maybe someone needs it. There is also the nginx_substitutions_filter module , which does the same thing, but can already search using regular expressions.
