I have a site whose home page shows a single WordPress category page. I'm using a custom theme and the index.php file there does a 301 redirect to "mysitename.com/?cat=3". This page is generated with the-events-calendar plugin and some custom code. It works, but the displayed URL is "mysitename.com/?cat=3" which I'd prefer my visitors not see; I'd rather have the URL be just "mysitename.com", "mysitename.com/index.php", or even "mysitename.com/calendar".
The visitor can view "prev month" and "next month", which result in URLs like "mysitename.com?cat=3&eventDate=2010-07&bt=a" -- still within the same category but with additional parameters in the URL. (I am OK having a more convoluted URL like this shown to my visitors on previous/next month; it's just the initial page URL I'd like to be nicer.)
I've messed around with the permalinks but can't get nice URLs to work correctly that way. Is there an .htaccess way to do this?
