Redmine

I study from :
http://www.redmine.org/wiki/redmine/HowTo_Install_Redmine_in_a_sub-URI_on_Windows_with_Apache

 Assuming that we will be hosting Redmine under http://localhost/redmine:
Edit C:\webserver\railsapps\redmine\config\environment.rb file to configure Redmine to work as a sub-URI (Apache configuration is also required and is listed later on in this document).

    * add the following line at the bottom of the file:

      Redmine::Utils::relative_url_root = "/redmine" 

    * save and close the file.

I add [Redmine::Utils::relative_url_root = "/redmine" ] to bottom of environment.rb

http://localhost/redmine is work, and css,js'link is changed

<link href="/redmine/stylesheets/application.css?1276138841" media="all" rel="stylesheet" type="text/css" />
<script src="/redmine/javascripts/prototype.js?1276138841" type="text/javascript"></script>
