Hi All,  
I have a rails application up and running. It’s working great. The one  
thing that bothers me is that when I embed urls in my pages, a lot of  
them are suffixed by ?, where number seems to be a timestamp.

E.g.: ![Logo](https://test.ruby-forum.com/images/logo.png?1163464174)

This has been generated by a simple:  
link\_to(image\_tag("/images/logo.png", :size =\> “355x130”) … )

This happens to a lot of other links, like stylesheet\_link\_tag,  
javascript\_include\_tag etc. It has never really broken functionality,  
but it doesn’t look nice.

Any ideas?

Thanks,  
Tom

Run your site in

```
RAILS_ENV=production

```

mode and see what happens. 😉

(That’s just a wild guess, folks!)
