Apache crashing when I add Far-Future Expires clause from Rails Guide
apache, ruby-on-rails, ruby-on-rails-3
Solution
What error does it give you? Are you sure you have mod_expires compiled into apache and that the module is loaded?
Invalid command 'ExpiresActive', perhaps misspelled or defined by a module not included in the server configuration
Yeah, that's usually the error you get if you use a directive that's mapped to a module that isn't loaded (or just a mispelled directive, which appears the same to apache). You'll need to check httpd.conf and make sure the `LoadModule expires_module modules/mod_expires.so` line is not commented out, of if it's missing, to add it. Depending on your apache's version, the line can be slightly different.
Problem
In an attempt to serve my precompiled assets with Apache, per this Rails Guide I try to change this: ``` <VirtualHost *:82> ServerName localhost DocumentRoot "C:/RubyStack-3.2.5-0/projects/release_checklist/public" <Directory "C:/RubyStack-3.2.5-0/projects/release_checklist/public"> Allow from all Options -MultiViews </Directory> ProxyPass / http://localhost:3001/ ProxyPassReverse / http://localhost:3001/ ProxyPreserveHost On </VirtualHost> ``` To this: ``` <VirtualHost *:82> ServerName localhost DocumentRoot "C:/RubyStack-3.2.5-0/projects/release_checklist/public" <Directory "C:/RubyStack-3.2.5-0/projects/release_checklist/public"> Allow from all Options -MultiViews </Directory> ProxyPass / http://localhost:3001/ ProxyPassReverse / http://localhost:3001/ ProxyPreserveHost On <LocationMatch "^/assets/.*$"> Header unset ETag FileETag None # RFC says only cache for 1 year ExpiresActive On ExpiresDefault "access plus 1 year" </LocationMatch> </VirtualHost> ``` in my `httpd.conf` file. However, the Apache server won't start when the second option has been added. What am I doing wrong?
