Some errors in apache proxy

[damulhan]

I want to use camaleon cms as apache web server proxy tunneling.

But some errors occurs. I cannot know how to do with it.

Direct accessing through port 3000 did not have errors.

The apache httpd.conf settings are like here:

<VirtualHost OO.OO.OO.OO>
        ServerName OOOOO 

        <IfModule mod_proxy.c>
        ProxyRequests On

        <Proxy *>
        Order deny,allow
        Allow from all
        #Require all granted
        </Proxy>

        <Location />
        ProxyPass http://127.0.0.1:8000/ retry=0
        ProxyPassReverse http://127.0.0.1:8000/
        </Location>

        </IfModule>
</VirtualHost>

Hi @damulhan
Looks like something is not configured well.
helpers/camaleon_cms/admin/application_helper.rb with module "CamaleonCms::Admin::ApplicationHelper" too.
Cheers!

Upper error was shown after patching by adding next lines in app/application_controller.rb like this:

class ApplicationController < ActionController::Base 
	skip_before_filter :verify_authenticity_token  
	protect_from_forgery prepend: true, with: :exception  
end

helpers/camaleon_cms/admin/application_helper.rb ... was never changed.

I added this option in apache conf. And it worked.
