I found the URL design page particularly interesting.

I have given URL design some thought. I should maybe write up the thinking behind the current design.

However, I've sometimes gotten frustrated because I felt that I couldn't reach a perfect design. And perhaps there is no right and wrong. Only trade-offs as in other types of design.

I want to implement URL rewriting so that I can fix bad URL design with HTTP redirects so that old links can keep working while still promoting the newer better design.
