Hi,

Why do I have ?1208641118 after my resources in production ?  
img alt=“Collapse” src="/images/collapse.gif?1208641118"

I’am sure the site is in production mode.

Thanks for your help,  
Mickael.

Rails does that with all of its asset links. The number is the  
modification date of the file (in seconds after something). The idea  
being that when you roll out an update that link will change to  
something different after the ? which forces the browser to get a new  
copy (rather than using a cached copy).

And you can turn if off by putting

# turn off time-stamping of static assets

ENV[‘RAILS\_ASSET\_ID’] = ‘’

in your config/environments/production.rb file.
