location /tslink/ {

        rewrite ^/tslink/(.+)/archive/(\d+)/(.+) /Mportal/server/api/chk_tmp_timeshift_link.php?key=$1&file=$3 break;
 
        proxy_set_header Host myhost; # 
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass http://myhost:88/; # 
    }
 
    location /archive/ {
        root /var/www; # <-- directory, where is archive folder (symlink RECORDS_DIR."archive")
        internal;
    }
 
    # is necessary to exclude "tslink" and "archive" section from the access to static files
    location ~* ^(?!(\/tslink|\/archive))\/.*\.(mpg|mpeg|avi|ts|mkv|mp4|mov|m2ts|flv|m4v|srt|sub|ass)$ {
 
        secure_link $arg_st,$arg_e;
        secure_link_md5 "supersecret$uri$remote_addr$arg_e";
 
        if ($secure_link = "") {
            return 403;
        }
 
        if ($secure_link = "0") {
            return 410;
        }
