this is a reverse-proxy connector that connects nginx to Railo. the files in this example assume that they are located in the same folder as the nginx executable file (i.e. nginx.exe on Windows).the main conf file is nginx-railo.conf which should be passed to nginx as the config file, e.g. nginx -c nginx-railo.confit includes other config files …

1 nginx-railo.conf

#### this is the main config file for nginx, to specify it from the command line, use the -c switch, e.g
####    nginx.exe -c nginx-railo.conf
