link_to problem

Hi,

having a problem with link_to. My rail app is running in a sub directory and when i use link_to for a file it does work, because link_to does not place the subdirectory path in the url, but if i go to another page first, then go back to the same page where the link_to is displayed it will display it properly and it will work. Really strange, can not seem to figure it out

BTW one thing i do notice on my server is that when my app goes displays the front page its in this format

http://www.domain.com/appname

instead of

http://www.domain.com/appname/

If i put the / at the end manually after the front page is displayed, everything works fine, but i cant seem to figure out how to make it do that automatically?
