+# Nginx proxy configuration for OpenNet
+
+Current implementation forward subdomains to following proxy locations:
+
+* `opennet.ru` > `/opennet`
+* `www.opennet.ru` > `/opennet/www`
+* `bsd.opennet.ru` > `/opennet/bsd`
+* `cisco.opennet.ru` > `/opennet/cisco`
+* `grab.opennet.ru` > `/opennet/grab`
+* `linux.opennet.ru` > `/opennet/linux`
+* `m.opennet.ru` > `/opennet/m`
+* `mobile.opennet.ru` > `/opennet/mobile`
+* `palm.opennet.ru` > `/opennet/palm`
+* `security.opennet.ru` > `/opennet/security`
+* `solaris.opennet.ru` > `/opennet/solaris`
+* `web.opennet.ru` > `/opennet/web`
+* `wiki.opennet.ru` > `/opennet/wiki`
+
+## Installation
+
+1. Download `nginx/opennet` to `/etc/nginx` folder
+2. Copy `nginx/opennet/server.conf` to `sites-available/opennet.conf`
+3. Alternatively, include `nginx/opennet/locations.conf` to existing website config at `sites-available` then reload nginx configuration
+
+## Issues
+
+1. At this moment, config drops all JS some tabs could not work
+2. Youtube embedded content still works
+3. Redirect cases not implemented yet and require additional rules implementation
