Problems with URL, strange.

Problems with my URL forwarding automatically for some reason. I believe it has to do with how my host has Apache setup. The problem is caused by simply leaving out the trailing slash in my blog URL: http://flipjarg.blinkenshell.org/blog/

Without the trailing slash: http://flipjarg.blinkenshell.org/blog the URL turns into blinkenshell.org/titan/~flipjarg/blog/ (titan is the server name) so I am wondering if there is a way to solve this with htaccess. I’ve tried forwarding with a simple PHP script I’ve used before but that failed.
