I have a simple config.ru rack app where I only require and run rack-server-pages to provide dynamic pages in a quick and convenient way. This config.ru app is served by phusion passenger-standalone (which uses nginx internally).
.erb files are processed and served correctly, except when I explicitely add the .erb extension to a URL (for a .erb file). In that case the server will send me the .erb file for download, rather than its output. Obviously I would like to avoid that.
To make it clearer:
The file on the server is called somefile.erb
this works:
www.domain.com/somefile
this sends the .erb file for download ☹:
www.domain.com/somefile.erb
How can I fix this? Is this a problem I should manage at the application level (rack-server-pages), or at the web server level (nginx configuration) ? In both cases I would need some help...
Update 2: I think this rack-server-pages file could be relevant... but it's just a wild guess and I wouldn't know what to change in it..
Update 1: Pasting passenger-standalone Nginx configuration file. Passenger-standalone uses Nginx internally, but with different settings than the system-wide Nginx at /etc/nginx/nginx.conf. The default settings for a passenger-standalone Nginx are regenerated at each passenger-standalone run based on the file at /usr/share/passenger/templates/standalone/config.erb. Following is that file:
##############################################################
# Phusion Passenger Standalone uses a template file to
# generate an Nginx configuration file. The original template
# file can be found by running the following command:
#
# ls $(passenger-config about resourcesdir)/templates/standalone/config.erb
#
# You can create a copy of this template file and customize it
# to your liking. Just make sure you tell Phusion Passenger Standalone
# to use your template file by passing the --nginx-config-template
# parameter.
#
# *** NOTE ***
# If you customize the template file, make sure you keep an eye
# on the original template file and merge any changes.
# New Phusion Passenger features may require changes to the template
# file.
