How to Remove /sitecore from the URLs?

I need to remove “/[sitecore]” from URLs because when I navigate to appropriate sites (www.site_name/sitecore) I will get empty page with no layout. I would like to ask you

  1. Is good option to use redirect to solve my problem ?

  2. Can this redirection of the “/sitecore” caused problems ? I found that in sites definition of my web config I have a lot of site definition like this: site name=“shell” virtualFolder="/sitecore/shell" physicalFolder="/sitecore/shell … where “/sitecore” is part of some other paths so I am not to solve it

Thanks in advance
