How do I do a URL rewrite of the Tableau server?

We have a requirement to customize the tableau server dashboard URL.

For example: Default URL of the tableau dashboard is "<servername>/#views/<dashaboardname>?:iid=1", We want to customize URL like this "<servername>/<dashboardname>".

I have found following code to do URL re-writing. Below is the code for the same.

# turn on the rewrite engine (module loaded above) #TABLEAU CODE

RewriteEngine on

...

⌗Rewrite the URL so that the server name does not appear #MY CODE

RewriteCond %{HTTP_HOST} !^(.*)[server name]\.[domain]\.com [NC]

RewriteCond %{HTTP_HOST} !^$

RewriteRule ^/(.*) name].[domain].com/$1 [R,L]

Can anyone please explain this ?

Thanks
