I have an interesting observation. I am using permanent links via .htaccess
1. http://myblog/blogname/2009/10/1/welcome , works (as it is supposed to)
2. http://myblog/blogname/2009/10/1/welcome/12345 , gives me the content of http://myblog/blogname/2009/10/1/welcome when the path is invalid
3. http://myblog/blogname/2009/10/1/welcome/12345/12345/ ,gives me a page with no content but other page features like header, footer are there.
Any ideas?. Should I add more rules to .htaccess
