I think that that statement is not specific enough for what you actually want. Because your html page "/unav/index.html" will include an image "/unav/img.png", and you want that not to count as "all requests". > But I think, I have solved it :) If this does what you want it to, that's good. When I tested, I saw some problems. > if ($remote_addr ~ '_admin_IP_') { > rewrite ^/(.*)$ /unav/$1 last; > } > > location ^~ /unav/ { > try_files $uri $uri/ /index.html; > } That will serve the content of /unav/index.html for all requests (unless you have an /unav/unav/img.png, for example), but it goes through lots of rewrites to get there. > location / { > > try_files $uri $uri/ @opencart; > } > > location @opencart { > rewrite ^/(.+)$ /index.php?_route_=$1 last; > } > > ... and so on ..... My suggestion: use "geo" or "map" or even "if" to set a variable $site_looks_down, which is "1" for users and "0" for admins. if that variable is true, do nothing special for /unav/* urls, and return 503 for the rest. have the 503 error return the content of /unav/index.html have /unav/index.html include links like /unav/img.png Overall, this is something like: http { geo $site_looks_down { default 1; 127.0.0.3 0; } server { if ($site_looks_down) { rewrite ^/unav/ $uri last; return 503; } error_page 503 /unav/index.html; location ^~ /unav/ { } # extra location{}s and server-level config here } } Now you can do things like curl -i http://127.0.0.1/unav/img.png curl -i http://127.0.0.3/unav/img.png and you should see the same image response, while things like curl -i http://127.0.0.1/sample/ curl -i http://127.0.0.3/sample/ should give you different responses -- one "503 unavailable", and one correct (maybe 404, maybe useful content). Change the "default" value to 0, or (better) just remove the if() block, to make the site available to all again. See documentation at things like http://nginx.org/r/geo for the syntax. f -- Francis Daly fran...@daoine.org _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
